HIV-1 interactions with cells: from viral binding to cell-cell transmission
1Department of Microbiology and Molecular Genetics, Medical College of Wisconsin, Milwaukee, Wisconsin, USA.
Abstract:
Characterization of HIV-1 interactions with host cells is critical for cell biology studies of HIV-1. This unit describes a set of methods and protocols to perform quantitative assays of HIV-1 binding, internalization, infection, and cell-cell transmission. The protocols include: (1) generating infectious single-cycle or replication-competent HIV-1 stocks, (2) an HIV-1 binding and internalization assay, (3) HIV-1 infection of target cells and quantification of viral infection, and (4) HIV-1 cell-cell transmission assays. These functional assays provide useful tools to quantitatively study HIV-1 infection and viral transmission.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
