What are Antigen-Presenting Cells and Their Role in Histology?
Antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B cells, play a pivotal role in initiating immune responses. They capture antigens, process them, and present them on their surface to T cells. In histology, the distribution and activity of APCs in tissues can be studied using specific markers. Understanding the localization and function of APCs helps in elucidating the mechanisms of immune responses in various diseases.
