Development of a human live attenuated West Nile infectious DNA vaccine: Suitability of attenuating mutations found in SA14-14-2 for WN vaccine design.

abstract：:We have previously described a selective increase in HIV-DNA content in CCR5-negative lymphocytes from late stage HIV-infected patients. Here, we show that this increase occurred even in the absence of viral phenotypic switching from CCR5- to CXCR4-tropic. This leads us to hypothesize that early and late CCR5-tropic v...

abstract：:Human parainfluenza virus type 2 phosphoprotein (P) is an essential component of viral polymerase. The P gene encodes both P and accessory V proteins by a specific gene editing mechanism. Therefore, the N-terminal 164 amino acids of P protein are common to V protein. Interestingly, while P protein is located in the cy...

abstract：:The sid (size determination) gene product of phage P4 is known to be involved in capsid-size determination. Moreover, the capsid-size determination function interferes with the lytic development of its helper P2, presumably because the helper genome is too large to be packaged into P4-size capsids. In order to study P...
