Summary
B7-H3, a molecule regulating T-cell responses, is increasingly found in human cancers. Its exact role in antitumor immunity remains unclear, despite evidence of both stimulatory and inhibitory functions.
Area of Science:
- Immunology
- Cancer Biology
- Molecular Biology
Background:
- B7-H3 is a recently identified member of the B7/CD28 superfamily.
- It modulates T-cell responses and is implicated in antitumor immunity.
- Its precise physiological role is still under investigation due to conflicting data.
Purpose of the Study:
- To summarize current data on B7-H3's role in T-cell response regulation.
- To focus on the potential function of B7-H3 in antitumor immunity.
Main Methods:
- Literature review of existing studies on B7-H3.
- Analysis of data regarding B7-H3 expression in cancer.
- Synthesis of findings on B7-H3's costimulatory and inhibitory capacities.
Main Results:
- B7-H3 expression is reported in various human cancers.
- B7-H3 has demonstrated both stimulatory and inhibitory effects on T-cells.
- Its role as a regulator of antitumor immunity is suggested but not fully elucidated.
Conclusions:
- B7-H3 is a key molecule in T-cell modulation with a potential role in cancer immunity.
- Further research is needed to clarify its dual function and therapeutic potential in oncology.

01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
01:24B Cell Activation and Differentiation
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

01:27Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
