PSMA Antibodies

Gene Name: PSMA (Prostate-Specific Membrane Antigen)

Function:

• PSMA is a cell surface glycoprotein that is highly expressed in prostate epithelial cells, particularly in prostate cancer cells.
• It plays a role in the internalization and metabolism of folate, as well as in cell adhesion, migration, and invasion processes.

Immune Regulation:

• PSMA expression on tumor cells may influence immune responses within the tumor microenvironment.
• Tumors expressing PSMA may exhibit altered immune cell infiltration, cytokine production, and immune checkpoint molecule expression.
• Targeting PSMA-positive tumor cells with immunotherapeutic approaches, such as monoclonal antibodies or CAR-T cell therapies, aims to enhance anti-tumor immune responses and overcome immune evasion mechanisms.

Apoptosis:

• While the direct role of PSMA in apoptosis regulation is not fully understood, dysregulation of PSMA expression or activity may impact apoptotic signaling pathways, contributing to cancer cell survival and tumor progression.

Research Implications:

• Understanding the functions of PSMA is essential for elucidating its roles in cancer development and progression.
• Research on PSMA may have implications for the development of targeted therapies and immunotherapies for PSMA-positive cancers, including prostate cancer and certain solid tumors.

Clinical Relevance:

• PSMA is a clinically validated biomarker and therapeutic target in prostate cancer.
• PSMA-targeted therapies, such as radioligand therapy (e.g., lutetium-177 PSMA radioligand therapy) and antibody-drug conjugates (ADCs), are being developed and evaluated in clinical trials for the treatment of PSMA-positive malignancies.
• Additionally, PSMA-directed CAR-T cell therapies are being investigated as a novel approach for treating PSMA-positive cancers, particularly in cases of treatment-resistant or advanced disease.
