Celgemedieerde

Celgemedieerde refers to biological processes that are mediated or carried out by cells. This term is broadly used in immunology and cell biology to describe how cellular interactions and functions contribute to various physiological and pathological events. In the context of immunology, celgemedieerde immunity is a crucial component of the adaptive immune response. It involves the action of T lymphocytes, such as cytotoxic T cells and helper T cells, which directly interact with infected or abnormal cells or orchestrate immune responses. Cytotoxic T cells, for example, recognize and kill virus-infected cells or tumor cells through direct contact. Helper T cells, on the other hand, release cytokines that activate other immune cells, including B cells and macrophages.

Beyond immunity, the concept of celgemedieerde processes extends to other areas of biology. For instance, cell-mediated signaling pathways describe how cells communicate with each other or respond to their environment through the release and reception of signaling molecules, often involving cell-to-cell contact or the action of secreted factors. Tissue repair and development also rely heavily on celgemedieerde mechanisms, where cells migrate, proliferate, and differentiate in a coordinated manner to form or regenerate tissues. Understanding these celgemedieerde processes is fundamental to comprehending normal biological functions and the mechanisms underlying various diseases.
