Fever: a rise in body temperature, usually caused by infection

Heat shock proteins (HSP): a family of proteins that are produced by cells in response to exposure to stressful conditions

Neutrophils: white blood cells that play an important role in inflammation and are early responders to pathogens.

T cells: major components of the adaptive immune system whose roles include regulating the immune response to pathogens.
