The main focus of drug carrier research today is to identify carriers that are both safe and effective for clinical treatment applications. As treatment strategies advance researchers regularly update drug delivery systems. Traditional drug delivery systems consist of liposomes and polymer micelles together with nanoparticles but despite their inclusion in clinical trials current versions still ...
Recombinant protein drugs refer to protein products that originate from animals and plants and are developed through biotechnology research. These protein drugs exhibit certain biological activity and can prevent, diagnose, and treat diseases in humans, animals, and plants. Compared with small molecular drugs, recombinant protein drugs offer advantages such as high activity, high specificity, and ...
T cells are the most numerous and functionally complex type of lymphocytes, mainly including CD4+ T cells and CD8+ T2 cells, which play an important role in cellular immunity and assist in humoral immune response. According to their functions in the immune response, T lymphocytes mainly include helper T cells (Th cells), regulatory T cells (Treg cells), effector T cells and cytotoxic T cells. ...
What are Adjuvants? Adjuvants, also known as immunomodulators or immune enhancers, are an additive to vaccines. Adjuvants are non-specific immune enhancers that enhance or alter the type of immune response to an antigen. Adjuvants can help antigens induce long-term effective specific immune responses in vivo, leading to higher vaccine efficacy and prolonged protection from immune responses. ...
Cytokines are a broad class of tiny proteins that are essential for controlling inflammation and immunological responses. Numerous cell types, including fibroblasts, endothelial cells, immunological cells, and epithelial cells, produce these signaling molecules. Serving as intermediaries, they synchronize various cell functions to elicit the body's defense mechanisms against infections, tissue ...
With the rapid development of antibody-drug conjugate (ADC), more and more companies have entered the field of ADC research and development, and various types of ADC technologies and branches have emerged. Bispecific antibody conjugates (BsAb ADCs) are one of the emerging new technologies. The high specificity of bispecific antibodies enables more precise targeting of tumor cells. On the other ...
Fc fusion protein (Fc-Fusion) has a complex and diverse molecular structure, and may contain glycosylation modification sites at amino acid 297 of its Fc fragment and the Fab region of some molecules. Moreover, its biological ligands are structurally diverse, and their glycosylation modifications may also be complex, usually involving multiple N-glycan and O-glycan sites and a large number of ...
Relationship Between Immunity, Inflammation and Cancer Immunity is an act of self-protection of the body. The immune response is divided into specific and non-specific. The antigen and antibody responses are generally referred to as specific immune responses, which require the participation of B cells and T cells. Other immune cells such as macrophages and NK cells mediate non-specific immune ...
Infectious diseases seriously threaten human health, and various infectious diseases may cause millions of severe cases and even death every year. Vaccination has been one of the most effective public health interventions in history, preventing millions of deaths worldwide. However, the success of vaccines relies not only on the antigens they carry but also on additional components known as ...
What is "click chemistry"? "Click Chemistry", this is a literary name given to this kind of reaction by the Nobel Prize winner K.Burry Sharless, when the cards are put together, "click" (click). Simply put, it is to add two structures to two molecules respectively, and these two structures can be specifically combined to synthesize the required chemical molecules. One of the most famous ...
In the past ten years, the number of antibody drug conjugates (ADCs) entering clinical trials has steadily increased. Currently, 9 ADCs have been approved, of which 5 are used for hematoma and 4 for solid tumor treatment. After more than 20 years of development, ADC biopharmaceuticals are becoming the main force in the treatment of cancer. Currently, one of the most important challenges when ...

Introduction to HLA Human leukocyte antigen (HLA) is a 3.6 Mb segment on the short arm of chromosome 6 that contains over 200 genes. It is also known as the major histocompatibility complex (MHC), and it is the most polymorphic region in the human genome, involving diverse immune reactions. HLA is divided into HLA-class I (corresponding to MHC class I) and HLA-class II (corresponding to MHC class ...
Self-amplifying RNA vaccines may induce equivalent or more potent immune responses at lower doses compared to non-repli- cating mRNA vaccines via amplified antigen expression. In this paper, we demonstrate that 1 mg of an LNP-formulated dual- antigen self-amplifying RNA vaccine (ZIP1642), encoding both the S-RBD and N antigen, elicits considerably higher neutral- izing antibody titers against ...
Cytokines are classified according to their different roles in the inflammatory response: pro-inflammatory cytokines and anti-inflammatory cytokines. Pro-inflammatory Cytokines Interleukin-1 (IL-1) IL-1 is a proinflammatory cytokine that activates a variety of immune and inflammatory cells and is secreted mainly by monocytes/macrophages, neutrophils and endothelial cells. IL-1 consists of two ...
The interesting SARS-CoV-2 omicron mutant strain evades immunity mediated by antibodies from vaccination or infection with early mutants due to the accumulation of a large number of spike mutations. Recently, in a research report titled "Structural basis of SARS-CoV-2 Omicron immune evasion and receptor engagement" published in Science, scientists from institutions such as the University of ...
The cornea is essential for vision yet highly sensitive to immune-mediated damage following infection. Generating vaccines that provide sterile immunity against ocular surface pathogens without evoking vision loss is therefore clinically challenging. Here, we tested a prophylactic live-attenuated vaccine against herpes simplex virus type 1 (HSV-1), a widespread human pathogen that can cause ...
The rise in recent decades of diseases such as inflammatory bowel disease and rheumatoid arthritis suggests that factors in the environment are contributing. In 1932, New York gastroenterologist Burrill Crohn described an unusual disease in 14 adults. The patients had bouts of abdominal pain, bloody diarrhea, and lesions and scars on the bowel wall. Doctors in other parts of North America and ...

Mechanically damaged cells release intracellular substances, resulting in the activation of CD4- and CD8-positive T-lymphocytes. The goal of this investigation was to quantify and compare fractions of activated CD4- and CD8-positive T-lymphocytes, based on the quantity of damaged cells in a given blood sample. Blood samples were mechanically stressed by vortexing intensely. Subsequently, ...
To address if the modulation of immunity balance by low dose radiation is involved in the enhancement of the anti-tumour function, we examined the effect of 0.5 Gy γ-irradiation on the Th1/Th2 immunity balance in Ehrlich Solid Tumour (EST)-bearing mice. Repeated 0.5 Gy γ-irradiation significantly delayed the growth of tumours. The cytotoxic activities of Natural Killer (NK) cells and Cytotoxic T ...
