Abstract
This letter refers to the recent demonstration that HIV-1 infected macrophages form specialized conduits that connect to B-cells (1). The conduit selectively transports the HIV-1 nef protein, providing nef with numerous means to interfere with cellular processes. Currently, no consideration of the connection between the conduit and the development of AIDS-related lymphoma (ARL) has been offered. ARL is one of the primary causes of death in the HIV-infected population and is related to B-cell proliferation and activation. In this letter we discuss several studies that link HIVinfected macrophages and specific forms of the nef protein to the development of ARL. The conduits discovered by Xu et al. [1] may lead to a better understanding of how HIV infection results in lymphomagenesis.

HIV vaccine development
The development of a safe and effective vaccine that impedes HIV-1 transmission and/or limits the severity of infection remains a public health priority. The HIV-1/AIDS pandemic continues to have a disproportionate impact on vulnerable and under-served communities in the USA and globally. In the USA, minority communities that have relatively ...read more
