The image shows a medical test vial labeled for PSA (Prostate-Specific Antigen), which is a protein produced by the prostate gland. The PSA test is commonly used as a tumor marker to screen for and monitor prostate cancer. The vial has a red cap and features a label with a QR code for clinical tracking and data management purposes. This test is crucial in the early detection of prostate cancer, allowing for timely intervention and management.

Antibody binding to human cell receptors is a crucial aspect of the immune response and plays a fundamental role in various physiological processes, including immune defense, signaling, and regulation of cellular functions. Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to the presence of foreign substances, such as pathogens or abnormal cells.

CAR T-cell therapy is a immunotherapy that uses genetically engineered T cells to intensify the immune systems response to cancer. T-cells with Chimeric antigen receptor recognize and kill the cancer cells in the body.

Lymphocytes such as T cells and B cells are part of the immune system

Cytotoxic T cell. T-cell regulate immune responses, release the perforin and granzymes, and attack infected or cancerous cells. Through the action of perforin, granzymes enter the cytoplasm of the target cell, and lead to apoptosis (cell death).
