Influenza Vaccine in Elderly: Nutritional Status-Dependent Immunogenicity

The immune response to influenza vaccine is attenuated in elderly persons, though they are at greatest risk for morbidity and mortality by influenza virus infection. Experimental studies demonstrate that co-administration of L-cystine and L-theanine enhanced antigen-specific production of immunoglobulin in aged mice infected with influenza virus. This study thus investigated (more…) RELATED ARTICLES TOP READ […]

Cystine & Theanine: Suppression of Exercise Induced Neutrophilia & Lymphopenia

Intense exercise induces increased blood neutrophil counts and decreased lymphocyte counts, and leads to inflammation and immunosuppression. It was previously reported that cystine and theanine (CT) supplementation by long-distance runners before training camp suppressed changes of these blood parameters observed in unsupplemented control subjects after the camp. This study examined (more…) RELATED ARTICLES TOP READ […]

Attenuation of Natural Killer T-Cells with Cystine & Theanine

Men who perform resistance training 3 times a week for at least 6 months tend to have lower T-helper cell counts than non–resistance trained men. In addition, the natural killer (NK) cell count, an index of innate immunity, has been shown to decrease below the resting value after submaximal resistance (more…) RELATED ARTICLES TOP READ […]
