1. Activate immune cell activity
Macrophages and natural killer cells:
Lactobacillus rhamnosus can directly eliminate pathogens by stimulating the phagocytic ability of macrophages and the activity of natural killer cells. Clinical data show that the respiratory infection rate of children decreased by 30%~40% after intervention.
Lymphocyte proliferation:
Promote the differentiation and proliferation of T lymphocytes and B lymphocytes, and enhance the efficiency of specific immune response.
2. Improve immunoglobulin levels
Mucosal immunity enhancement:
Induce the production of secretory IgA (sIgA) in the intestines and respiratory tract, strengthen the defense function of the mucosal barrier, and inhibit the invasion of pathogens.
Systemic immune activation:
Significantly increase the concentration of immunoglobulins such as IgG and IgM in serum, and enhance the systemic anti-infection ability.
3. Regulate the balance of immune response
Th1/Th2 balance regulation:
Inhibit Th2 overactivation, reduce IgE-mediated allergic reactions, and relieve symptoms such as eczema and allergic rhinitis by 65%.
Cytokine network regulation:
Promote the secretion of α-tumor necrosis factor (TNF-α), interleukin 6 (IL-6) and IL-10 by peripheral blood mononuclear cells, and optimize immune signal transduction.
4. Strengthening the intestinal barrier and flora synergy Physical barrier protection:
Promote the expression of intestinal epithelial tight junction proteins (such as ZO-1) to reduce systemic inflammation caused by toxins entering the blood.
Microbial barrier construction:
Maintain intestinal flora homeostasis by competitively inhibiting the colonization of pathogenic bacteria such as Escherichia coli and Salmonella, and indirectly reduce the burden on the immune system.
Typical application scenarios Children's immune enhancement:
Long-term supplementation can reduce the incidence of colds by 45% and increase the efficiency of vaccine antibody response by 20%.
Allergic disease intervention:
After taking it for 8 weeks continuously, the serum IgE level of allergic patients decreased by 38%.
Respiratory tract infection prevention:
Specific strains (such as CRL1505) regulate the intestinal-lung axis to reduce the risk of upper respiratory tract viral infection
