HER-2 (Human Epidermal Growth Factor Receptor 2), also known as ERBB2. is a transmembrane tyrosine kinase receptor involved in regulating cell proliferation, survival, and differentiation. Overexpression or amplification of HER-2 occurs in 15-20% of breast cancers and some gastric, ovarian, and lung cancers, driving aggressive tumor growth and poor prognosis. This molecular alteration makes HER-2 a critical therapeutic target.
HER-2-targeted antibodies, such as trastuzumab (Herceptin®) and pertuzumab (Perjeta®), bind specifically to HER-2 extracellular domains, inhibiting downstream signaling pathways like PI3K/AKT and MAPK. Trastuzumab, the first FDA-approved HER-2 antibody (1998), also recruits immune cells to induce antibody-dependent cellular cytotoxicity (ADCC). These therapies revolutionized treatment for HER-2-positive cancers, significantly improving survival rates. However, primary or acquired resistance remains a challenge, prompting development of antibody-drug conjugates (ADCs) like trastuzumab emtansine (T-DM1) and trastuzumab deruxtecan (T-DXd), which deliver cytotoxic payloads directly to cancer cells.
Diagnostically, HER-2 status is assessed via immunohistochemistry (IHC) for protein expression and fluorescence in situ hybridization (FISH) for gene amplification, guiding treatment decisions. Ongoing research focuses on combination therapies, novel ADCs, and strategies to overcome resistance, solidifying HER-2 antibodies as cornerstones of precision oncology.
