Autoimmune Diseases: Causes, Examples and Mechanisms of Action
Autoimmune Diseases: Causes, Examples and Mechanisms of Action Introduction Autoimmune diseases occur when the body's immune system mistakenly attacks its own cells, tissues, or organs. This happens due to a breakdown in the immune system’s ability to distinguish between self and non-self antigens. These diseases can affect various parts of the body, including joints, skin, muscles, and even internal organs. Understanding...
Major Histocompatibility Complex (MHC): Importance in Antigen Presentation
Major Histocompatibility Complex (MHC): Critical Role in Antigen Presentation and Immune Recognition Introduction The Major Histocompatibility Complex (MHC) is a crucial component of the immune system responsible for antigen presentation to T cells. This complex plays a vital role in distinguishing self from non-self, which is essential for immune responses against pathogens, tumors, and transplanted tissues. In this study module, we will...
Cytokines and Their Role in Immune Regulation
Cytokines: Key Regulators of Immune Responses and Their Clinical Significance Introduction Cytokines are small proteins that play a crucial role in immune regulation and communication between cells. They act as signaling molecules that modulate immune responses, inflammation, and hematopoiesis. These molecules are produced primarily by immune cells such as macrophages, lymphocytes, and dendritic cells, and they influence both innate and adaptive...
