Liposome Drugs Show Potential Therapy Effectiveness
A novel liposome product, doxorubicin hydrocholoride liposomal injection, has received FDA approval as well as European Commission authorization to be used in the treatment of a variety of cancers, including ovarian cancer, acquired immune deficiency syndrome (AIDS)-related Kaposi's sarcoma, and multiple myeloma. It is no doubt another piece of good news for patients as well as researchers around the world. Although considerable research in the last several decades on liposomes has gained significant advancement, further demonstrating the significant potential of liposome drug development, more research in the diverse applications of liposome drugs is still required to be conducted in the future. Liposomes as drug delivery carriers have attracted much attention due to their multiple advantages, such as their biocompatibility, which can protect pharmaceuticals from the inactivating effect of external conditions but not cause undesirable side reactions, and their potential slow-release or targeting properties. Among most of the novel drug delivery carriers, liposomes are considered the best ones. Therefore, a great deal of research on liposome development has progressed rapidly in recent years, including the development of liposomal formulations and functional liposomes. Liposomal formulations have a key role in the development of liposome drug delivery compared to general formulations, which can be utilized to overcome the non-ideal properties of drugs, including limited solubility, serum stability, circulation half-life, biodistribution, and target tissue selectivity. Liposome formulations have advantages in a variety of disease fields, including tumors, infections, neurology, anesthesia, ophthalmology, and diagnosis. Liposome-encapsulated drugs have 50%–70% lower tumor toxicity than free drugs, and liposome formulations have higher tumor suppressor activity than free drugs. Furthermore, functional liposome development is as important as the development of liposomal formulations. Liposomes can be used for specific applications by using appropriate surface functionalization and modification technology, such as extending circulation time, increasing cellular uptake, and increasing tumor site payload accumulation, for which the functional liposome provides key benefits in disease treatment. The growing demand for functional liposomes drives the continuous and rapid development of global biotechnology, and biotech companies all over the world are engaged in fierce competition to capture the abundant market share.

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. Glycan identification involves determining the precise chemical structure of a carbohydrate based on different pieces of evidence, such as molecular weight or size and chemical properties. Techniques used in glycan identification often include Mass Spectrometry or Nuclear Magnetic Resonance (NMR), which allow researchers to map out the exact composition of a glycan and establish an identification profile that aids future studies. After purifying and identifying glycans, scientists often utilize anti-glycan antibody assays to further their understanding of biological systems. Anti-glycan antibody assays aim to detect antibodies produced against specific glycans. These antibodies are typically a part of the immune response against pathogens, disease progression, or vaccination. Detecting these antibodies can provide valuable insights into the immune response and help researchers understand and intervene in disease states. For instance, in the case of cancer, abnormal glycan structures are often present on tumor cells. Identifying these glycans and the antibodies that recognize them helps scientists develop targeted therapies and diagnostics. Similarly, anti-glycan antibodies play a pivotal role in investigating and combating infectious diseases, where pathogens often use glycans to invade host cells. Anti-glycan antibody assays use various technologies to detect these antibodies, including enzyme-linked immunosorbent assays (ELISA), Western blotting, and microarray technologies. These assays all rely on the specific binding of an antibody to its corresponding glycan to produce a detectable signal, signifying the presence of the antibody. In conclusion, glycan purification, glycan identification, and the anti-glycan antibody assay play a significant role in elucidating the functionalities of glycans in life and health sciences. These processes underpin the essential research into diseases, their treatments, and further advancements in the field of glycobiology. Continued investment in improving these methodologies will grant broader insight into the incredible potential glycans hold for medicine and biology, equipping scientists with the necessary tools to further unravel the complex puzzle of glycans.
Gamma Delta T-Cell Based Cancer Immunotherapy Gives Patients Great Hope
Cancer has been a leading cause of death worldwide for decades, accounting for nearly one in every six deaths and posing a serious threat to people's health. A great number of plans and approaches have been approved to support the improvement of cancer cure rates with ongoing research on cancer treatment. A recent study demonstrated that γδ T-cells were found to be the most prognostically beneficial immune cell subset in tumor infiltrates from 18,000 tumors across 39 malignancies, which makes γδ T-cells a kind of highly promising effector cell compartment for cancer immunotherapy. At present, γδ T cells have indicated powerful anti-tumor efficacy against breast cancer, colon cancer, lung cancer, leukemia, and others. As innate immune cells, indeed, gamma delta T cells can recognize tumor cells independently of human leukocyte antigen (HLA) restriction and quickly produce abundant cytokines and potent cytotoxicity in response to malignancies. Gamma delta T cells have several favorable features for the development of T cell-based therapy for cancer, which are listed below: * Gamma delta T cells recognize a broad spectrum of antigens on various cancer cells. * Gamma delta T cells recognize their target cells independent of the major histocompatibility complex (MHC). * Gamma delta T cells are distributed in various tissues and can quickly respond to target tumor cells. * Gamma delta T cells interact with other immune cells such as B cells to drive a cascade of immune responses against tumors. Isolating and purifying functional and specific gamma delta T cell populations from a complex biological sample is crucial for understanding the biological function of gamma delta T cells and creating gamma delta T cell-based therapies. Therefore, outstanding technologies for T cell isolation play a critical role. Magnetic bead cell sorting (MACS) is a frequent, efficient, and quick method for isolating uncontaminated gamma delta T lymphocytes from human peripheral blood mononuclear cells (PBMCs). In addition, due to the essential function of gamma delta T cells in several diseases, a T cell cytotoxicity test is necessary for testing gamma delta T cell activity and cytotoxicity. The normal cytotoxicity tests include the LDH cytotoxicity test, flow cytometry-based cytotoxicity test, and impedance-based label-free real-time cytotoxicity assay, in which the LDH cytotoxicity test is one of the most commonly used methods for cell cytotoxicity detection.

A Promising Cancer Therapy：Gamma Delta T Cell-Based Cancer Immunotherapy
In recent years, gamma delta T cells have raised a lot of expectations to be applied in tumor and cancer treatment for their exceptional abilities to recognize and kill transformed cells independently of human leukocyte antigen restriction. And there has been increasing interest in translating their potential characteristics into innovative cellular cancer immunotherapies. Despite the high potential of gamma delta T cells, the efficacy of gamma delta T cell immunotherapy is currently limited, with a lower response rate. In order to advance gamma delta T cell immunotherapy, global biotech companies pull out all their efforts, trying to make some achievements, as Creative Biolabs did. Recent studies showed that gamma delta T cell repertoires (TCRs) provide the basis for their applications in cancer treatment. Analyzing the TCR repertoires may help to gain a better understanding of the immune system's features and of the aetiology and progression of diseases, in particular those with unknown antigenic triggers. However, the TCR receptor diverges widely, resulting in a severe challenge to the work of analysis. As a result, scientists have created a number of analysis methods to provide a practical and effective way for gamma delta TCR repertoire analysis, including sanger sequencing, polymerase chain reaction assays, and flow cytometry. Additionally, researchers must also conduct an investigation of the gamma delta TCR-ligand reaction before they can identify whether the ligand has a high affinity for the gamma delta TCR and further assess the effectiveness of the developed gamma delta T cell therapy. With the boom of biological techniques, several methods such as surface plasmon resonance, isothermal titration calorimetry, and X-ray crystallography are widely utilized for the identification and analysis of TCR-ligand reactions. More importantly, the need for TCR generation plays a role in boosting gamma delta T cell therapy. Whether it is αβ T cells or γδ T cells, the activation and various functions of T lymphocytes are both mediated by the surface TCR. Therefore, the significance of TCR generation does not require more explanation. As an expert in gamma delta T cell therapy development, Creative Biolabs has assembled a group of elite scientists and established a unique development platform to ensure each project's success. The company provides a comprehensive set of services regarding gamma delta T cell immunotherapy and tailored services based on customers' needs, including but not limited to gamma delta T cell repertoire analysis, TCR-ligand reaction analysis, and generation services.
