Sleep Could Help Fight Against Infection- Study

Sleep could enhance the target ability of immune cells inside human body to help fight off infection, a recent study revealed on Thursday

Sleep is a naturally recurring state of mind and body, characterised by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings.

According to the study published on Tuesday in the Journal of Experimental Medicine, the finding shows that sleep has the potential to enhance the efficiency of effector T-cell responses.

Researchers said that compared with the wake condition, sleep significantly increased the mean fluorescence intensity of T cells, a type of white blood cell that fights off infection inside human body.

“Our results demonstrate that a couple of hours of sleep loss suffice to reduce the adhesion capacity of antigen-specific T cells.

“The findings could help develop new therapeutic strategies with the aim of improving the target ability of T cells, especially when they are killing tumor cells,’’ the study added.  (Xinhua/NAN)
