Macrophages: Functions, Mechanism, Significance
Macrophages are one of the major types of white blood cells or leukocytes of the immune system that play an important role in the innate immune response against pathogens, foreign substances, cancer cells, and cellular debris. What Are Macrophages? Where Do They Come From? How Do They Work? Origins and Development of Macrophages Some of […]
Thymus: Functions and Significance
The thymus is a primary lymphoid organ located behind the sternum, between the upper portions of the lungs, and in front of the heart. As part of the immune system, it is primarily responsible for the maturation and differentiation of a specific type of white blood cells or leukocytes called thymus leukocytes or T cells. […]
T Cells Explained: Roles and Types of Thymus Lymphocytes
Thymus lymphocytes or T cells are a specific type of white blood cells or leukocytes developed in the thymus organ that play a central role in the immune response and the adaptive immune system. Specifically, T cells attack cells infected by a pathogen, activate other immune cells, and produce cytokines and chemokines, while also playing a […]
What are Chemokines: Role in Immune Response
Chemokines are small proteins that form a specific class or subgroup of signaling molecules called cytokines. Note that the word “chemokines” is a neologism for “chemotactic cytokines” coined in 1992 during the Third Symposium on Chemotactic Cytokines. Note that “chemotaxis” pertains to the movement of an organism or cells in response to a chemical stimulus […]
Role of Cytokines: Immunomodulating Agents
Cytokines are immunomodulating agents responsible for regulating the immune response. They are produced and secreted by certain immune and non-immune cells. More specifically, they are a broad and loose category of small proteins that collectively function as a significant communication mechanism used by the immune system and the body in general. Functions and Roles in […]
