Antimicrobial peptides play an important role in human innate defense against microbial pathogens. LL-37 is the only member of the human cathelicidin family of antimicrobial peptides. We previously showed that LL-37 targets the cell wall of Candida albicans, thereby reducing cell adhesion to plastic surfaces, oral epidermoid cells, and urinary bladders of mice. Moreover, LL-37 also induces cell wall and endoplasmic reticulum stress responses. Here, we found that LL-37 alters plasma membrane properties. In addition, LL-37 affected calcium homeostasis and induced the generation of reactive oxygen species associated with mitochondria and vacuoles. Finally, the Rim101 pathway was linked to the cellular response to LL-37. Together, these findings provide new insights into anti-C. albicans actions of LL-37 and highlight the complex cellular responses induced by LL-37.
