Natural killer cells in hepatitis B virus infection BJID
Wu,Shao-fei; Wang,Wen-jing; Gao,Yue-qiu.
Natural killer cells are a unique type of lymphocytes with cytotoxic capacity, and play important roles against tumors and infections. Recently, natural killer cells have been increasingly valued in their effects in hepatitis B virus infection. Since hepatitis B virus is not cytopathic, the subsequent antiviral immune responses of the host are responsible for sustaining the liver injury, which may result in cirrhosis and even hepatocellular carcinoma. Many studies have confirmed that natural killer cells participate in anti-hepatitis B virus responses both in the early phase after infection and in the chronic phase viacytolysis, degranulation, and cytokine secretion. However, natural killer cells play dichotomic roles: they exert antiviral and...

The role of natural killer cells in the early period of infection in murine cutaneous leishmaniasis BJMBR
Laurenti,M.D.; Gidlund,M.; Ura,D.M.; Sinhorini,I.L.; Corbett,C.E.P.; Goto,H..
In order to study the role of natural killer (NK) cells during the early period of Leishmania infection, BALB/c mice were selectively and permanently depleted of NK cells by injection with 90Sr and subsequently infected with Leishmania (Leishmania) amazonensis (HSJD-1 strain). 90Sr is known to selectively deplete NK cells, leaving an intact T- and B-cell compartment and preserving the ability to produce both interferon alpha and IL-2. This method of depletion has advantages when compared with depletion using anti-NK cell monoclonal antibodies because the effect is permanent and neither activates complement nor provokes massive cell death. In the present study, after one month of treatment with 90Sr, the depletion of NK cells was shown by a more than...
