The immune system relies on a network of ligands and receptors for communication. Examples include cell surface ligands like MHC molecules and CD proteins, secreted ligands like cytokines and chemokines, as well as various types of receptors. These interactions play a crucial role in immune surveillance, activation, and regulation.

Oh, Look…More Lymphocytes
The immune system involves more than just T cells, B cells, and ILCs. Other important lymphocyte populations include NK cells, γδ T cells, MAIT cells, DN T cells, LTi cells, IELs, and Tregs. These cells have diverse functions, such as detecting and eliminating infected or tumor cells, recognizing non-peptide antigens, contributing to tissue development, and regulating immune responses.
How Are Innate Lymphoid Cells Different Than B Cells and T Cells?
Innate Lymphoid Cells (ILCs) are a unique group of immune cells distinct from B and T cells. Unlike the adaptive immune system cells, ILCs respond rapidly to signals of tissue damage or infection, do not undergo antigen-specific selection, and contribute to tissue homeostasis. They lack specific antigen receptors and are part of the innate immune system.
