Aspergillus fumigatus is an important cause of pulmonary and systemic infections in immune compromised individuals, and of corneal ulcers and blindness in immune competent patients. To examine the role of chitin synthases in Aspergillus corneal infection, we analyzed Aspergillus mutants of chitin synthase family 1 and family 2, and found that the quadruple mutants from both families were more readily killed by neutrophils in vitro, and that both exhibited an impaired ability to grow in the cornea. Further, inhibition of chitin synthases using Nikkomycin Z enhanced neutrophil killing in vitro and in vivo in a murine model of A. Read More

Thymic stromal lymphopoietin (TSLP) is an interleukin 7 (IL-7)-like four helix bundle cytokine that plays diverse roles in the regulation of immune responses. In fungal infection, pattern recognition receptors (PRRs), including the cell surface Toll-like receptors (TLRs) and cytoplasmic NOD-like receptors, recognize pathogen-associated molecular patterns to initiate downstream signal cascades to active immune responses. Our previous studies reported that, in vitro human cornea epithelium cells represented a novel target of TSLP and that TSLP/TSLPR/STAT5 signaling played an important role in the response to Aspergillus fumigatus challenge.
