Recently, researchers have found that fever can promote the transfer of lymphocytes to the infected site. They explain that this is because fever increases the expression of heat shock protein 90 (Hsp90) in T lymphocytes, which binds to integrins and promotes T lymphocytes to adhere to blood vessels and eventually accelerate migration to the site of infection.
Not only fever, but also other stress can induce the expression of Hsp90 in T lymphocytes cannot support the above conclusion.
