Human dermcidin (DCD) is synthesized as a 110-amino acid precursor (pre-dermcidin, pre-DCD) containing a 19-residue leader signal sequence, which is removed to produce a leader-less pro-domain-containing peptide termed as pro-dermcidin, pro-DCD. Pro-DCD can be secreted by human eccrine sweat glands and then cleaved into antimicrobial peptides, such as dermcidin (DCD). Emerging evidence suggests that pro-DCD has broader physiological roles beyond antimicrobial defense, potentially serving as a therapeutic agent for inflammatory diseases like sepsis. In this review, we summarize recent evidence supporting pro-DCD as a regulator of innate immunity in sepsis.
人皮肤杀菌肽（DCD）最初被合成为一种含110个氨基酸的前体（前皮肤杀菌肽，pre-DCD），其包含一个19个残基的前导信号序列，该序列被去除后产生一种不含前导序列但含前结构域的肽，称为前皮肤杀菌肽原，pro-DCD。Pro-DCD可由人外分泌汗腺分泌，然后裂解为抗菌肽，如皮肤杀菌肽（DCD）。新出现的证据表明，pro-DCD除了具有抗菌防御作用外，还具有更广泛的生理作用，可能作为脓毒症等炎症性疾病的治疗剂。在本综述中，我们总结了最近支持pro-DCD作为脓毒症中固有免疫调节因子的证据。
