Cytokines immune system

The term "cytokine" is derived from a combination of two Greek words - "cyto" meaning cell and "kinos" meaning movement. Cytokines are cell signalling molecules that aid cell to cell communication in immune responses and stimulate the movement of cells towards sites of inflammation, infection and trauma.

Pathogen infections are recognized by the immune system, which consists of two types of responses: an innate immune response that recognizes pathogen-associated molecular patterns (PAMPs) and an antigen-specific adaptive immune response. In both responses, there are several activated cells of the immune system, which play a key role in establishing the environment of cytokines, thus directing their differentiation either suppressing or promoting the immune response. This immune response is…

Local and systemic actions of pro-inflammatory cytokines👇 📎Pro-inflammatory cytokines play crucial roles in both local and systemic immune responses. Here's a breakdown of their actions: 📌Local Actions: 🔴Inflammation Initiation: Pro-inflammatory cytokines such as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) are produced by immune cells (e.g., macrophages) at the site of infection or tissue damage. 🔴Vasodilation and Increased Permeability: Cytokines…
