Reactive lymphocyte surrounded by red blood cells. Reactive lymphocytes or variant lymphocytes are cytotoxic (CD8+) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 Âµm in diameter with varying size and shape. The nucleus of a reactive lymphocyte can be round, elliptic, indented, cleft, or folded. The cytoplasm is often abundant and can be basophilic.
C-reactive protein is an annular, pentameric protein found in blood plasma, whose levels rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. Its physiological role is to bind to lysophosphatidylcholine expressed on the surface of dead or dying cells in order to activate the complement system via C1q. CRP is synthesized by the liver in response to factors released by macrophages and fat cells (adipocytes). It is a member of the pentraxin family of proteins. It is not related to C-peptide (insulin) or protein C (blood coagulation). C-reactive protein was the first pattern recognition receptor (PRR) to be identified.
