[Effect of heart benefiting recipe in controlling IL-1beta, IL-6 and APPmRNA expression in brain of beta-amyloid protein induced rat model of dementia].

OBJECTIVE

To investigate the neuro-immune regulatory mechanism of Heart Benefiting recipe (HBR), an effective recipe for treatment of Alzheimer's disease (AD).

METHODS

Using immunohistochemical and RT-PCR methods, the neuro-immunological pathological changes in the AD rat model induced by beta-amyloid protein (A beta1-40) via lateral cerebral ventricle injection, including mainly the glial fibrillary acidic protein expression and inflammatory cytokines IL-1beta, IL-6mRNA and beta-amyloid protein precursor (APPmRNA) gene expression were studied. And the effects of HBR on these parameters were observed.

RESULTS

Deposition of A beta in cerebral tissue could induce activation of stellate glial cells and abnormal increased levels of inflammatory cytokines (IL-1beta and IL-6mRNA), also the elevation of APPmRNA level. HBR could effectively control the above-mentioned pathological changes.

CONCLUSION

HBR could effectively control the inflammation and the A beta immune cascade reaction in brain of AD patients, it is one of the important therapeutic mechanisms of the recipe.
