iPSC-derived Cell Therapy Development
In the stem cells therapy, the induced pluripotent stem cells (iPSCs) which are directly derived from patients' somatic cells reprogramming to an embryonic-like state. Since iPSCs could be coaxed into the desired cell types that would already be genetically matched with the patient, the immune rejection and the ethical issues can be potentially circumvented.
Understanding the Role of Glycans in Biological Research
Glycans, also known as carbohydrates or polysaccharides, are fundamental constituents of all cellular life. They play essential roles in various biological processes, including cell-to-cell communication, immune response, and disease progression, among others. Accurate glycan purification, glycan identification, and anti-glycan antibody assays are crucial in advancing our understanding of glycans and their roles in biology and medicine. Glycan purification is a critical initial step in the study of glycans. It is the process of extracting and isolating glycans from an organism or cell culture to make them available for further study. Purification allows researchers to separate glycans for individual analysis and remove unwanted materials that may interfere with the results, thus increasing the accuracy of any subsequent procedures. Various methodologies are utilized in glycan purification, dependent on the type, structure, and purpose of analysis, ranging from chromatographic separation techniques to enzymatic methods. Once glycans are purified, the next essential step is glycan identification. Glycans are notorious for their structural complexity and heterogeneity. Hence, they pose unique challenges in terms of their identification and characterization.

Decoding the Potential of Immune Checkpoint Therapy: Antibody Development and Assays
The intricacies of the human immune system have been profoundly explored in recent years, revealing a wealth of knowledge that has unlocked new opportunities and methodologies for fighting diseases. One promising discovery is the concept of immune checkpoint therapy. The technology and mechanisms necessary for immune checkpoint antibody development have been under intense focus, which offers hope for groundbreaking therapies and disease management. Immune checkpoint therapy is a form of cancer therapy that utilizes the body's immune system to identify and fight diseases. This innovative treatment targets the 'checkpoints' within the immune system, which function as protective barriers to prevent immune cells from attacking other healthy cells in the body. Some cancers, however, have found ways to manipulate this protective mechanism, evading the immune system by mimicking these checkpoints. By targeting these checkpoints, the revolutionary therapy aims to enhance the body's immune response against cancer cells, enabling the immune system to effectively target and destroy these cells. The successful application of immune checkpoint therapy hinges on a crucial prerequisite: the precise development of immune checkpoint antibodies. These antibodies play a vital role in enhancing the patient's immune response toward cancer cells. By binding to the immune checkpoints and blocking them, these antibodies enable the immune system to recognize and attack cancer cells. Therefore, the seamless development of these antibodies is crucial to shaping the effectiveness of immune checkpoint therapy. Modern biotechnology and genomic methods have allowed scientists to create antibodies specifically tailored to target these immune checkpoints. Immune checkpoint antibody development is characterized by rigorous processes that involve identifying the appropriate gene for therapy, replicating it, and then engineering cells to produce these antibodies. Another crucial aspect of this development is ensuring these antibodies can effectively bypass the immune system checkpoints while avoiding potential damage to healthy cells. In the quest to streamline and accurately measure the immune response, scientists have developed immune checkpoint assays. These investigative tools provide a platform for assessing how effectively an immune system can trigger a response against cancer cells. Assays are crucial in examining the efficacy of immune checkpoint therapies. By studying key immune responses, researchers can make informed predictions about how a patient's immune system will respond qualitatively and quantitatively to a particular therapy. Immune checkpoint assays, therefore, play a pivotal role in facilitating the design and optimization of therapeutic strategies that target and manipulate immune checkpoints. They offer researchers essential insights that guide the development of immune checkpoint therapies. In conclusion, the pioneering field of immune checkpoint therapy has profoundly impacted cancer treatment paradigms. The development of immune checkpoint antibodies, coupled with the precision afforded by immune checkpoint assays, heralds a new dawn in the fight against cancer and various other diseases. As research continues to unearth and perfect these innovations, there is substantial hope for the development of even more effective and personalized treatments to fight cancer and other immune-related diseases.
The Promising Revolution of Immune Checkpoint Therapy in Biotechnology
Investigations in the biotechnology arena have been dramatically transforming the dimensions of healthcare, particularly in the cancer treatment sector. Notably, prominent growth has been witnessed in the field of immune checkpoint therapy, which is revolutionary in treating several forms of cancer. To understand immune checkpoint therapy, one must comprehend the concept of immune checkpoints. In a normal functioning body, immune checkpoints are imperative for maintaining self-tolerance and thus, preventing the immune system from attacking cells indiscriminately. They serve as "brakes" for the immune system, ensuring it does not act aggressively against normal cells in the body. The most researched immune checkpoints are namely Cytotoxic T-Lymphocyte-associated protein 4 (CTLA-4) and Programmed cell death protein 1 (PD-1). However, cancer cells are known to exploit these checkpoints, hiding from the immune system by imitating a command found on normal cells and hence, preventing the immune system from destroying them. This is where immune checkpoint inhibitors step into the limelight. Immune checkpoint inhibitors are drugs - often made of antibodies - that can unleash an immune system attack on cancer cells. By doing so, they disrupt the signals produced by cancer cells that deceive the immune system. In essence, immune checkpoint inhibitors "remove the brakes" and unmask the cancer cells, allowing the immune system to readily recognize and destroy them by utilizing their natural anti-cancer activities. One of the commonly used immune checkpoint inhibitors is the CTLA-4 inhibitor. CTLA-4 is an immune checkpoint located on T cells (the warriors of our immune system), which when activated, downregulates immune responses. In cancer treatment, CTLA-4 inhibitors work by blocking this checkpoint, thereby enhancing the immune responses against cancer cells. It's worth noting that the first immune checkpoint inhibitor to gain FDA approval was Ipilimumab, a CTLA-4 inhibitor that has shown promising results against melanoma, a type of deadly skin cancer. With the advent of immune checkpoint therapy, the tides have turned in cancer treatment. Unlike conventional therapies that directly attack the cancer cells, immune checkpoint therapy cleverly enables the body's own immune system to eliminate cancer cells, paving a promising path towards the use of immunotherapies in oncological treatments. Yet, the complexity lies in the heterogeneous response observed in patients undergoing immune checkpoint therapy. While some patients showcase excellent responses, others appear resistant or develop adverse reactions. Hence, further research is ongoing to elucidate more about the complex biology behind immune checkpoints and the application of their inhibitors, enabling personalized therapy based on individual responses. In conclusion, the progress and developments in immune checkpoint therapy have undoubtedly reshaped the landscape of cancer treatment and hold immense potential for the future. As the realms of Biotechnology and Immunology continue to interwind, a new era of not only effectively treating but potentially curing cancer seems on the horizon.

Promising Gammadelta T Cells for Cancer Therapy Research
The field of cancer research has been remarkably transformed in recent years, with a significant emphasis placed on the potential of immunotherapy. Central to these advancements has been a unique subset of immune cells known as gammadelta (γδ) T cells. These T cells are gaining attention due to their innate ability to detect and destroy tumor cells. Additionally, they can be manipulated through T-cell engineering, opening the door to cancer treatments. T-cell engineering represents a quantum leap in medicine's ability to restructure components of our immune system to fight cancer cells more effectively. While most current therapies have focused on Alpha Beta (αβ) T cells, γδ T cells present unique characteristics that make them attractive alternatives. These include their ability to detect and eliminate a broad spectrum of malignancies without causing graft-versus-host disease. An appealing development in this field has been the construction of CAR-engineered γδ T cells. The CAR approach equips γδ T cells with synthetic receptors that can recognize specific antigens in cancer cells. These are 'homing devices' that direct the engineered T cells toward tumors. The CAR engineering technology has been combined with γδ T cell activation. This process enhances the tumour-recognizing capabilities, causing the γδ T cells to proliferate and attack cancer cells more efficiently. Gammadelta T cell activation is an essential aspect of developing effective CAR-engineered γδ T cell therapies. When activated, these cells have the potential to initiate a robust immune response. They display a potent cytotoxic function, target multiple cancers, and show long-term persistence in the body, making them ideal warriors in the fight against cancer. Practical implementation of this targeted approach necessitates rigorous testing, which brings researchers to the γδ T cell cytotoxicity test. In these tests, the γδ T cells' ability to recognize and kill cancer cells after being engineered and activated is evaluated. During the γδ T cell cytotoxicity test, the performance of the CAR-engineered γδ T cells is scrutinized under various conditions, including different cancer types and levels of malignancy. Moreover, γδ T cell cytotoxicity testing has been pivotal in revealing some significant advantages these cells have over other immune cells. For instance, γδ T cells respond to a wide range of cancers, including those resistant to other immunotherapies. They also persist longer in the body and are less prone to exhaustion, where T cells lose their ability to function over time. In conclusion, the research focused on CAR-engineered and activated γδ T cells is breaking new ground in studying immunotherapy for cancer treatment. The tireless efforts to fine-tune T cell engineering, improve methods of γδ T cell activation, and refine the γδ T cell cytotoxicity test are heralding promising prospects for the future. While challenges remain, the unique potential of γδ T cells in cancer therapy provides a beacon of hope, arguably becoming one of the most exciting frontiers in cancer research today. The promise of developing more personalized, durable, and efficacious cancer therapies is no longer a far-off vision, bringing real hope to researchers around the world.
Bacterial Polysaccharides and Their Research Innovations
Bacteria are covered by polysaccharides at the outer surface in the form of capsules, glycoproteins, or glycolipids. Such a bacterial sugar coat constitutes the principal antigens in most pathogenic bacteria and plays an important role in host-pathogen interactions. With more understanding of polysaccharide biosynthesis and its interplay with polymer modification and synthesis, scientists have recognized the research potential of polysaccharides in developing novel antibacterial strategies and novel applications like epidemiological markers. Bacterial polysaccharides mainly are carbohydrates like capsular polysaccharides (CPS) and lipopolysaccharides (LPS). Capsular polysaccharides are highly-hydrated homo- or hetero-polymers that are composed of repeating sugar units joined by glycosidic linkages. They usually are inserted into the cell surface of bacteria by covalent attachments to either phospholipid or lipid-A molecules. Lipopolysaccharide, on the contrary, is a membrane component characteristic of Gram-negative bacteria consisting of lipid A, core-oligosaccharide, and O-polysaccharide (or O-antigen) joined by a covalent bond. With a series of advanced technologies, including chemical degradation techniques, nuclear magnetic resonance spectroscopy, and mass spectrometry techniques, researchers now can comprehensively carry out structural characterization and analysis of bacterial polysaccharides and understand their functions. CPS usually constitutes the outermost layer of the cell and gets involved in mediating interactions between bacteria and the environment, for which polysaccharide capsules are implied as important virulence factors for several bacterial pathogens. Moreover, CPS can protect bacteria from phagocytosis if the pathogen is attacked by innate immune responses. Capsular polysaccharides prevent the activation of phagocytosis by decreasing antibody opsonization and masking ligands for phagocytic cell attachment. Therefore, polysaccharides antibodies as biomarkers have become the research hotspot in the field of disease diagnosis and treatment. Researchers at the Queensland University of Technology have successfully characterized the genomic loci in Acinetobacter baumannii that are responsible for cell-surface polysaccharide synthesis and have proven them to be effective epidemiological markers to track A. baumannii. Lipopolysaccharides are large molecules localized in the outer layer of the bacterial membrane and populate much of the cell surface. LPS can establish a permeability barrier, protecting bacteria from toxic molecules such as antibiotics and bile salts. In addition to being a key component of the cell envelope, LPS also contributes to host-pathogen interactions with the innate immune system. Bacterial adaptive changes, including modulation of LPS synthesis during chronic infection, could protect disease by preventing phagocytosis and adhesion to epithelial cells with O-antigen lipopolysaccharide or enhancing host immune response evasion with a production of less immunogenic lipid A, etc. In some cases, the immune response against the bacterial polysaccharide could be too dramatic to be toxic to the host, which confers protection against the disease in some depth. Polysaccharides could also be found in fungi and yeast in the form of glucans, chitin, and mannans, playing a major role in the cell wall structure. Current research on fungal polysaccharides mainly aims at identifying influential factors for their biological activity and elucidating their interactive role in various chemical medicine. The biological activities of fungal polysaccharides are shown to influence anti-tumor, anti-microbial, immune-stimulation or immunomodulatory activity, nutritional component, and hypoglycemic activity. With more understanding of the structure of various polysaccharides, details about the mechanism of action of polysaccharides in different systems are being revealed. Polysaccharides of bacteria and fungi will share more extensive applications in diagnostics and therapeutics.
Therapeutics for Leukemia: Targeting Cancer-associated Glycans
The inception of cancer immunotherapy could be traced back to the 19th century when the 'Father of Cancer Immunotherapy', William Coley, successfully led spontaneous regression of tumors by developing erysipelas with the injection of Coley's toxins into cancer patients. Different from cytotoxic chemotherapy, cancer immunotherapy allows targeted therapies, which fight against cancer by exploiting the effector mechanisms of the immune system. Current therapeutic strategies have put more emphasis on coordinating the adaptive immune responses and anti-cancer immunotherapies, but these therapeutics often cause resistance and associated severe toxicities. Therefore, it's increasingly necessary to find alternative therapeutics to adaptive immunity-based immunotherapy, in the process of which the contributions of the innate immune effectors to anti-tumor immunity are growingly recognized. Hazard of Existing immunotherapies for Leukemia Immunotherapies are a promising option for treating leukemia compared with modern chemotherapy regimens that have many side effects. Cancer immunotherapies usually induce cancer remission in a long term by leveraging components of the immune system, in which antibodies have been taken as the best candidates for cancer immunotherapy use due to less off-target toxicities. Currently, three categories of immunotherapies, including antibody-drug conjugates (ADCs), bispecific T-cell receptor-engaging (BITE) antibodies, and CAR-T cells are approved for the treatment of relapsed/refractory (R/R) acute leukemias. But these therapeutics for leukemia are greatly limited by resistance, toxicity, and applicability. Another shortcoming of existing immunotherapies is the incapability of eradicating cancer stem cells (CSCs). Glycans in Cancer Glycans are part of the immune system's components that can distinguish self from danger. However, cancer cells can make use of the total set of glycans in a biological species to adapt to and escape from the selection pressure exerted by the immune system. This process is called aberrant glycosylation and universally exists in all tumor cells, producing immunogenic glycans that are generally known as tumor-associated carbohydrate antigens (TACAs) or cancer-associated glycans. Cancer-associated glycans takes an important part in cancer cell signaling, tumor cell dissociation and invasion, cell-matrix interactions, angiogenesis, metastasis and immune modulation, so from cancer-associated glycans researchers can identify that cancer cells have acquired cancer hallmark capabilities. The hallmarks of aberrant glycosylation in leukemia and other cancer cells include sustaining proliferative signaling, evading growth suppressors, deregulating cellular energy, resisting cell death, enabling replicative immortality, activating invasion and metastasis, inducing angiogenesis, genome instability, and mutation, tumor promoting inflammation, and avoiding immune destruction. Moreover, it's proven that aberrant glycosylation is related to tumor initiation, progression, and metastasis, so it could be a new hallmark of cancer development. Targeting Glycans in Leukemia Therapy Researchers noticed that lectins can preferentially bind to carbohydrates, highlighting the significance of lectin-glycan interactions in the living system. Lectins have become one of the best candidates for the detection, isolation, and characterization of glycoconjugates, as well as for drug delivery to the site of action due to their ability to bind specific sugar residues in glycoproteins and glycolipid complexes. What's more, lectins can also be applied to distinguish malignant tumor cells from normal cells by recognizing modified glycan structures that are mainly expressed on the surface of tumor cells. Different from adaptive immune resistance that makes it possible for cancer cells to evade tumor-specific T-cell responses, the innate immune lectins as alternatives can specifically distinguish self from non-self cells and work as crucial defenders without replying on adaptive immunity for pathogen clearance. Considering that expression change of cell-surface glycans caused by the malignant cells is an intrinsic target for lectin recognition, the glycosylation landscape of leukemia and the clinical significance of lectins binding to leukemic blasts have long been an interest to researchers. Thus, the lectin pathway of recognizing cancer's aberrant glycans makes it a canonical component of the innate immune system, which can be exploited in targeting cancer-associated glycans as a therapeutic strategy in leukemia, as well as other cancer immunotherapies.
