Background The coronavirus-19 disease (COVID-19) pandemic reminds us of the
importance of immune function, even in immunologically normal individuals. Multiple …

Background. To investigate the association of individual lifestyle with immune response
against tumors, we assayed peripheral blood lymphocytes of 62 healthy males ranging in …

The function of natural killer (NK) cells in inflammation has not been explored enough in
large-scale population studies. The cross-sectional and time-dependent relationship …

Purpose Several studies have reported relationships among physical activity, healthy
metabolic status, and increased natural killer (NK) cell activity. However, large-scale data …

Increasing evidence has demonstrated that the immune system closely interacts with other
physiological systems, whose communications are mediated by circulating cytokines and …

Natural Killer cells are cytotoxic lymphocytes that recognize and eliminate tumor cells.
Exercise enhances NK cell cytotoxic activity (NKCA), yet the underlying mechanisms are not …

Background: Natural killer (NK) cells play a role in natural immunity against tumor and
infected cells. Advanced aging is associated with functional impairment of NK cells and …

Background. Regular exercise has been reported to slow the age-associated declines in
natural killer cell activity (NKCA). To evaluate this response, we recruited older …

Design: Non-randomized study. Objective: To determine natural killer cell cytotoxic activity
(NKCA) to 2-h arm ergometer exercise in persons with spinal cord injuries (SCI) and the …

The effect of acute exercise on natural killer (NK) activity and on the distribution of
phenotypic characteristics of peripheral blood lymphocytes was examined. Trained and …
