https://www.selleckchem.com/products/evobrutinib.html Venezuelan, eastern, and western equine encephalitis viruses (VEEV, EEEV, and WEEV) are mosquito-borne viruses in the Americas that cause central nervous system (CNS) disease in humans and equids. In this study, we directly characterized the pathogenesis of VEEV, EEEV, and WEEV in cynomolgus macaques following subcutaneous exposure because this route more closely mimics natural infection via mosquito transmission or by an accidental needle stick. Our results highlight how EEEV is significantly more pathogenic compared to VEEV similarly to what is observed in humans. Interestingly, EEEV appears to be just as neuropathogenic by subcutaneous exposure as it was in previously completed aerosol exposure studies. In contrast, subcutaneous exposure of cynomolgus macaques with WEEV caused limited disease and is contradictory to what has been reported for aerosol exposure. Several differences in viremia, hematology, or tissue tropism were noted when animals were exposed subcutaneously compared to prior aerosol exposure studies. This study provides a more complete picture of the pathogenesis of the encephalitic alphaviruses and highlights how further defining the neuropathology of these viruses could have important implications for the development of medical countermeasures for the neurovirulent alphaviruses.Due to diverse pathogenic potentials, there is a growing need for anti-HCMV agents. In this study, we show that treatment with DAPT, a γ-secretase inhibitor (GSI), impairs HCMV replication as assessed by a progeny assay based on immunostaining. This effect is not limited to DAPT because other GSIs with different structures and distinct mechanisms of action also exhibit a similar level of inhibitory effects on HCMV viral production, indicating that γ-secretase activity is required for efficient HCMV replication. Western blot and qPCR analyses reveal that DAPT does not interfere with the viral entry process, but reduces e
