Medullasin enhances human natural killer cell activity.
Medullasin, a new serine protease found in bone marrow cells, increased markedly human natural killer cell activity. Whereas the natural killer cell activity measured immediately after the treatment with medullasin remained almost on the same level as the control, an incubation at 37 degrees C for several hours increased markedly the natural killer cell activity of the lymphocytes treated with ...
متن کاملCocaine increases natural killer cell activity.
The administration of epinephrine to humans increases natural killer (NK) cell activity and numbers. If endogenous catecholamines regulate NK cells, then their activity should be increased by cocaine, an agent that potentiates endogenous catecholamines. We investigated the in vivo effect of cocaine on NK cell activity and on the distribution of lymphocyte subsets, including NK cells. Intravenou...
متن کاملModulation of Natural Killer Cell Activity
Natural killer (NK) cells are a heterogenous subpopulation of peripheral blood lymphocytes (PBL) that have the ability to kill various tumors and tumor cell lines in the absence of prior sensitization. These cells have generated considerable interest and have been implicated in natural resistance to tumors,'-5 resistance to viral infection:-7 transplantation rejection,'** and immunoregulation o...
متن کاملIncreased Natural Killer Cells Activity in Schizophrenic Patients
Background: Schizophrenia has been associated with altered immunity. Different studies regarding natural killer cell activity (NKA) in schizophrenic patients have shown inconsistent results. Objectives: To evaluate NK cell activity in schizophrenic patients in comparison with healthy control individuals. Methods: 30 medication-free schizophrenic patients and 41 healthy sex, age and smoking st...
متن کاملDiminished helper/suppressor lymphocyte ratios and natural killer activity in recipients of repeated blood transfusions.
Immunologic abnormalities qualitatively similar to those seen in acquired immunodeficiency syndrome (AIDS), including a low helper/suppressor lymphocyte ratio and low natural killer (NK) activity, have been observed in many hemophiliacs receiving clotting factor concentrates. To determine whether these changes also occur after repeated blood transfusion, we measured helper/suppressor (T4/T8) ra...
