Abstract
HIV-1 replicates by infecting new target cells either as cell-free viral particle or, much more efficiently, via cell-to-cell viral transmission. Cell-mediated viral spread, in which the infected cell directly transfers the viral particles to target cells via cell-cell contacts, in vitro is up to three orders of magnitude more efficient than transmission mediated by cell-free viral particles. Because of its potency, it has been suggested that current antiretroviral treatments could be less effective in blocking cell-to-cell viral transmission than cell-free. In this review, I will present an overview of the drugbased antiretroviral approaches as well as how the recently identified class of anti-HIV-1 broadly neutralizing antibodies could become part of an effective anti-viral strategy. I will discuss how both treatment strategies can be guided by our consideration that cell-to-cell HIV-1 spread is a major route of viral spread also in vivo.

New drug therapy for eye diseases
Eyesight is one of the most critical senses, accounting for over 80% of our perceptions. Our quality of life might be significantly affected by eye disease, including glaucoma, diabetic retinopathy, dry eye, etc. Although the development of microinvasive ocular surgery reduces surgical complications and improves overall outcomes, medication therapy is ...read more
