Abstract

In general, exercise can help improve overall health and prevent diseases. However, individuals with atopic dermatitis (AD) often lose the desire for physical exercise owing to itching caused by sweating. In the present study, we have evaluated the effect of low-intensity tower climbing resistance exercise (TCRE) on Dermatophagoides farinae extract (DFE; house dust mite extract)- and 2,4-dinitrochlorobenzene-induced AD-like skin lesions in a BALB/c model. Histopathological examination showed reduced thickness of the epidermis/dermis and dermal infiltration of inflammatory cells in the ears. TCRE downregulated serum Ig levels and suppressed mRNA expression of pro-inflammatory cytokines in the ear tissue, and reduced the size and weight of draining lymph nodes (dLNs) and nondraining lymph nodes (ndLNs), along with expression of pro-inflammatory cytokines in CD4+T cells from dLNs and ndLNs. Taken together, we showed that low-intensity TCRE reduced AD symptoms. These results will help improve treatment of AD, and will be of interest to dermatologists as well as to patients with AD.
