简要总结

A bidirectional relationship among nutrition, infection and immunity exists: changes in one component affect the others. Various micronutrients are essential for immunocompetence, particularly vitamins A, C, D, E, B2, B6, and B12, folic acid, iron, selenium, and zinc. Micronutrient deficiencies are a recognized global public health issue, and poor nutritional status predisposes to certain infections. Immune function may be improved by restoring deficient micronutrients to recommended levels, thereby increasing resistance to infection and supporting faster recovery when infected. Diet alone may be insufficient and tailored micronutrient supplementation based on specific age-related needs is necessary.

Aim of the study is to investigate whether nutrient supplementation may affect different functional parameters of the innate and adaptive immunity.

详细描述

Study objective:

The study is designed to evaluate the effects of Bioritmon Immuno Defend on the immune response of healthy subjects.

The following parameters will be evaluated:

PBMC proliferative response to polyclonal mitogens as described
Expression of CD69 on mononuclear cells by flow cytometry before and after polyclonal stimulation as described
Th1/Th2 cytokine cytoplasmic expression in PBMC before and after polyclonal stimulation
Evaluation of NK cytotoxicity by NKTEST Tm BD Biosciences
Evaluation of neutrophil phagocytic activity by PHAGOTESTTm BD Biosciences
Evaluation of neutrophil oxidative burst by PHAGOBURST Tm BD Biosciences
Evaluation of neutrophil chemotaxis by MIGRATEST Tm BD Biosciences
Measurement of serum cytokines (IL2, IL4, IL6, IL10, IFNgamma, TNF) by solid phase assay as described
