THE PROGNOSTIC VALUE OF BULK DISEASE IN TREATMENT OUTCOMES OF PE DIATRIC HODGKIN LYMPHOMATREATED ACCORDING TO EURONET PROTOCOL

Fungal keratitis (FK) is a serious corneal infection caused by pathogenic fungi. Monocyte chemoattractant protein-induced protein 1 (MCPIP1) plays an important role in restricting the inflammatory response in various immune disorders. However, the function of MCPIP1 in Aspergillus fumigatus (A. fumigatus) keratitis is unclear. In the present study, we found that A. fumigatus infection promotes the expression of MCPIP1 in human corneal epithelial cells (HCECs) and in mouse corneas. Overexpression of MCPIP1 decreased the production of inflammatory cytokines, including TNF-α, IL-6, and IL-1β, while knockdown of MCPIP1 increased the expression of these cytokines. MCPIP1 enhanced autophagy flux by inhibiting the mTOR signaling in HCECs with A. fumigatus infection. Further study showed that inhibition of autophagy using chloroquine reverses the anti-inflammatory effect of MCPIP1 in HCECs infected with A. fumigatus. Moreover, MCPIP1 alleviated the severity of keratitis and inhibited the expression of inflammatory cytokines by activating autophagy in an FK mouse model. In conclusion, our study demonstrated that MCPIP1 alleviates the severity of A. fumigatus keratitis by inducing mTOR-mediated autophagy in HCECs and in a mouse model. Exogenous use of MCPIP1 protein may have potential applications in FK clinical therapy.
