Description

technical field

[0001] The invention relates to the technical field of microbes, in particular to a strain of Bifidobacterium lactis with immune regulation activity. Background technique

[0002] Immunity is a physiological function of the human body, which involves non-specific immunity and specific immunity. Non-specific immunity does not require prior contact with antigens. Once pathogens enter the body, they will quickly eliminate pathogens. Both phagocytes and natural killer cells have clearance and killing functions, and are important members of the non-specific immune system. Specific immunity has immune cells (T lymphocytes and B lymphocytes) that specifically recognize foreign substances and have immune memory capabilities. The most important information transducers between the immune system are cytokines, each of which has different stimulating functions on different cell types, and they induce the growth and functional activity of cells by binding to specific rec...
