8 Differences between cytokines and chemokines

Differences between Cytokines and Chemokines

Differences between Cytokines and Chemokines Here are some differences: S.N. Characteristics Cytokines Chemokines 1. Definition Small proteins produced dominantly by immune cells which are important in cell signaling. Specific cytokines that are specially adapted for chemotaxis of cells. 2. Description A broad family of chemical messengers serving to bring about the immune response. They are chemotactic cytokines. 3. Size ~5–20 …

Cytokines- Mechanism of action and Functions

Cytokines Cytokines are a family of small proteins that mediate an organism’s response to injury or infection. Cytokines operate by transmitting signals between cells in an organism. Minute quantities of cytokines are secreted, each by a single cell type, and regulatory functions in other cells by binding with specific receptors. Their interactions with the receptors produce secondary signals that inhibit …

Innate Immune System- An Introduction

Introduction The innate immune system provides the first line of host defense against microbes, before adaptive immune responses have had sufficient time to develop. The mechanisms of innate immunity exist before exposure to microbes. The cellular components of the innate immune system include epithelial barriers and leukocytes (neutrophils, macrophages, NK cells, lymphocytes with invariant antigen receptors, and mast cells). The …
