Mild Fever Enhances Effectiveness of CD8+ T-cells

Scientists have found that the generation and differentiation of CD8+ cytotoxic T-cell is enhanced by mild fever-range hyperthermia. Specifically, their research suggests that elevated body temperature changes the T-cells’ membranes which may help mediate the effects of micro-environmental temperature on cell function. To test this, researchers injected two groups of mice with an antigen, and examined the activation of T-cells following the interaction with antigen presenting cells. Body temperature in half of the mice was raised by 2 degrees centigrade, while the other half maintained a normal core body temperature. In the warmed mice, results showed a greater number of the type of CD8 T-cells capable of destroying infected cells. Read more in the Journal of Leukocyte Biology.
