Although the worldwide incidence of HIV infection is high, the retrovirus displays a surprisingly low infectivity in vitro. As a potential explanation for this discrepancy, Münch et al. (2007) now identify and characterize a factor found in human semen that under certain conditions can enhance HIV infectivity by more than 100,000-fold.
尽管全球范围内HIV感染的发生率很高，但这种逆转录病毒在体外的感染性却出奇地低。作为对这种差异的一种潜在解释，明希等人（2007年）现在鉴定并描述了一种在人类精液中发现的因子，在某些条件下，它可将HIV的感染性提高超过10万倍。
