Studies were performed to investigate the effects of the endogenous opioid peptide methionine enkephalin on experimental metastasis of the murine B-16 melanoma and on murine splenic natural killer cell activity. Methionine enkephalin was shown to significantly inhibit tumor metastasis and significantly enhance splenic natural killer cell activity. These results indicate that the endogenous opio...
Background: Regarding the immunomodulatory effects of lactobacillus bacteria, this study aimed to evaluate the effect of oral administration of Lactobacillus reuteri, as probiotic bacteria, on natural killer cell cytotoxicity and tumor-specific lymphocyte proliferation in Balb/c mice with breast adenocarcinoma. Methods: A total of 30 female mice, aged 6- 8 weeks and with a weight of approximat...
The X-linked lymphoproliferative syndrome is characterized by immunodeficiency to Epstein-Barr virus (EBV) manifested by severe or fatal infectious mononucleosis and acquired immunodeficiency. We studied immune responses in six males of a well-characterized kindred with the X-linked lymphoproliferative syndrome. Two males were studied before and during acute fatal EBV infection. Both individual...
Consistent reports of the positive relationship between regular physical activity and immunosenescence have generated much excitement in the field of exercise immunology. It is generally accepted that natural killer (NK) cell activity per NK cell decreases with age; decreases in NKCA have been associated with infection and death in the aged. The effects of exercise and training on natural kille...
