Thus, we could postulate that the shift from a Th2 to a Th1 response (increased Th1 cytokines and decreased Th2 cytokines) might be partly Outer membrane C/OmpC Protein Species responsible for the reduced allergic immune response. With regards to IFN-, Pecaut and colleagues suggested that the serum concentration was considerably decreased for the duration of a 3-week period of 3G hypergravity3. Nonetheless, as they utilised stationary handle animals (mice housed in stationary cages), the impact of rotatory strain could not be ruled out. In our study, group C showed significant down-regulation of IFN- soon after normogravity rotation. Soon after long-term exposure to hypergravity, the expression of IFN- was restored to a standard level. As biological activity of IFN- is also associated with promotion of Th1 differentiation and suppression of Th2 differentiation, the boost of IFN- immediately after exposure to hypergravity could also be responsible for the shift from a Th2 to a Th1 response. To confirm the impact of chronic hypergravity around the allergic inflammatory response in the lung plus the nasal cavity, we performed a histopathologic examination. As there was a substantial reduce within the number of inflammatory cells that had infiltrated into lung parenchyma and nasal mucosa, we could confirm histologically that chronic hypergravity could alleviate allergic asthma and rhinitis. The mechanism of hormetic effect of chronic hypergravity still remains largely unveiled17. One of the hypotheses is that protection and repair mechanisms against the pressure might be involved17. As a result of elevated metabolic rate as a result of increased weight, there may be much more oxidative harm consequently. As a result, activities of a number of anti-oxidant enzymes may be upregulated to safeguard an organism against this oxidative damage17. To be able to investigate this hypothesis in our model of allergic inflammation, we evaluated the expression of many genes connected with anti-oxidative and anti-apoptotic function. The Bcl-2 family members comprises proteins involved within the intrinsic apoptotic Periostin, Human (758a.a, HEK293, His) pathway. Among them, Bcl-2 is definitely an antiapoptotic aspect, and Bax is amongst the proapoptotic factors. In our study, the expression of Bcl-2 was considerably suppressed and that of Bax was significantly enhanced right after exposure to chronic hypergravity. Suppression of antiapoptotic enzymes and enhancement of proapoptotic enzymes could be responsible for improved apoptosis (and decreased number) of inflammatory cells within the lung parenchyma and nasal cavity. A decrease of inflammatory cells, in turn, may be accountable for the decreased Th2 cytokines. Our results and ideas are in agreement with these of previous research. Lin and colleagues suggested that IL-21 treatment brought on lowered allergic symptoms, enhanced apoptosis of Th2 lymphocytes, and a substantial decrease with the antiapoptotic factor Bcl-2 in allergic mice23. Zhao and colleagues reported that the expression of Bcl-2 was considerably enhanced in patients with allergic rhinitis. They stated that the expression of Bcl-2 was increased in CD4+ T lymphocytes and endothelial and epithelial cells24. Alternatively, the expression of Bax and caspase-3 mRNA was substantially improved in allergic mice25. Thus, a protective impact of chronic hypergravity against allergic inflammation may be related to the downregulation of antiapoptotic signals (Bcl-2) and upregulation of proapoptotic signals (Bax) in inflammatory cells like eosinophils,.
