Abstract

Invasive fungal infections threat the life of immunocompromised patients. Chromogranin A N‑46 (CGA-N46), corresponding to the 31st to 76th amino acids of the N‑terminus of human chromogranin A, is an antifungal peptide. In order to elucidate the antifungal effects of CGA‑N46 in vivo, we studied its effects on cell‑mediated immunity in Candida krusei‑infected mice. The results showed that the treatment with CGA‑N46 increased the average body weight and decreased the mortality of the immunocompromised mice model infected with Candida krusei. The spleen and thymus indices of treated mice has markedly increased compared with that of the control group (P<0.05), and the immune cell levels in peripheral blood also increased significantly (P<0.05). The immuno‑modulatory effect of CGA‑N46 (60 mg/kg/day) was found to be comparable to that of terbinafine. Additionally, CGA‑N46 could alleviate or eliminate histopathological symptoms in the liver, spleen, kidney, and lung tissues. In conclusion, the present study suggests that CGA‑N46 may offer a new strategy for antifungal therapeutic option. This study is an essential step in elucidating the effect of CGA‑N46 in vivo.
