Fever is a state of elevated body temperature, one of the most common signs of infections caused by viruses, bacteria or parasites. Despite the heat and dizziness it causes, fever is actually in alliance with the body's immune system to fight these pathogens, CAS researchers reported online 15th January in Immunity, that fever in mice can alter membrane proteins on immune cells like T cells to enhance their ability to enter infection sites or lymph nodes. These immune cells can either directly march into the battle field of the infection or learn to recognize the enemies in the lymph node before joining the battle. In either case, a stronger army of immune cells will gather at the infection site,and lead to a quicker clearance of the pathogens.
