Mosquito salivary proteins ( MSPs ) modulate the host immune response , leading to enhancement of arboviral infections . Identification of proteins in saliva responsible for immunomodulation and counteracting their effects on host immune response is a potential strategy to protect against arboviral disease . We selecte... | West Nile virus ( WNV ) is a mosquito-borne flavivirus found on all continents except Antarctica .

A... | The ATR-ATRIP complex is recruited to sites of DNA damage by replication protein A-bound single-stranded DNA ( RPA-ssDNA ) , and controls cellular responses to various types of DNA damage . The recruitment of ATR-ATRIP to RPA-ssDNA is not sufficient for the kinase activation . The activation of ATR-ATRIP requires activ... | [

Pandemic HIV-1 originated from the cross-species transmission of SIVcpz , which infects chimpanzees , while SIVcpz itself emerged following the cross-species transmission and recombination of monkey SIVs , with env contributed by the SIVgsn/mus/mon lineage that infects greater spot-nosed , mustached and mona monkeys . ... | Use of an entry coreceptor , in conjunction with CD4 , is the main determinant of HIV/SIV cell targeting , which in turn may be a central factor determining pathogenicity of infection .
