Receptors are proteins, usually cell surface receptors, which bind to ligands and cause responses in the immune system, including cytokine receptors, growth factor receptors and Fc receptor. Receptors can be found in various immune cells like B cells, T cells, NK cells, monocytes and stem cells
There are two types of receptors: internal receptors and cell-surface receptors.
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. … Intracellular receptors are those found inside the cell, and include cytoplasmic receptors and nuclear receptors
