If the cell moves away from the extracellular matrix, signaling through these receptors stops, and the cell undergoes apoptosis. oncologist. Unlike internal receptors that can be found within the cytoplasm and can directly alter DNA, cell-surface receptors need to transmit signals through signal transduction. Antiangiogenesis is a form of treatment that disrupts the blood supply to the tumor (anti- means against, angi/o means vessel, and -genesis means reproduction). Direct signaling (also called juxtacrine signaling) involves communication between cells that are in direct contact with each other. Then, a signaling cascade is triggered within the T cell, triggering varying cellular responses, including the recruitment of other immune cells, the proliferation, and differentiation of T cells, or the killing of infected or cancerous cells. __________ is a diagnostic test to detect damage or malformations of the lymphatic vessels.
