Recently, researchers have discovered that fever can promote the transfer of lymphocytes to the site of infection
Not only fever, other pressure can also induce the expression of Hsp90 in T lymphocytes
 They explained that this is because fever increases the expression of heat shock protein 90 (Hsp90) in T lymphocytes, this protein binds to integrins , T lymphocytes adhere to blood vessels and eventually accelerate their migration to the site of infection
