B7-H3 protein (CD276) is overexpressed in tumors, making it a promising target for cancer immunotherapy. Strategies targeting B7-H3 show potent antitumor activity and good safety in preclinical models.
Area of Science:
- Oncology
- Immunology
- Molecular Biology
Background:
- Immunotherapy is a key cancer treatment strategy.
- B7 homolog 3 protein (B7-H3, also known as CD276) is a promising target due to its tumor-specific overexpression.
- B7-H3 influences the tumor microenvironment (TME) and cancer development.
Purpose of the Study:
- To review the expression and biological function of B7-H3 in various cancer and normal cells.
- To explore B7-H3-mediated signaling pathways in cancer.
- To summarize B7-H3-based cancer immunotherapy strategies.
Main Methods:
- Literature review of B7-H3 expression and function.
- Analysis of B7-H3 signaling pathways.
- Compilation of preclinical and clinical data on B7-H3 immunotherapies.
Main Results:
- B7-H3 is highly expressed in numerous tumor types but minimally in normal tissues.
- B7-H3 plays a significant role in shaping the TME and promoting tumor growth.
- Various B7-H3-targeted immunotherapies have shown efficacy in preclinical settings.
Conclusions:
- B7-H3 is a validated target for cancer immunotherapy.
- Targeting B7-H3 offers a promising therapeutic avenue with demonstrated antitumor effects.
- Further research into B7-H3-based strategies is warranted for clinical application.
