HIV-1 establishes immediate latency in T cells expressing the viral Nef protein. [PDF]

FEBS Open Bio
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Inhibition of Protein Synthesis by the Human Immunodeficiency Virus Type 1 nef Gene Product

Journal of General Virology, 1994
During productive infection of human T lymphocytes in cell culture, the expression of human immunodeficiency virus type 1 is temporally regulated by virus-encoded regulatory proteins. Among these Nef, whose function has not been clearly elucidated, is thought to alter CD4+ T cells.

Regulation of HIV-1 transcription in cells of the monocyte-macrophage lineage

Retrovirology, 2009
Human immunodeficiency virus type 1 (HIV-1) has been shown to replicate productively in cells of the monocyte-macrophage lineage, although replication occurs to a lesser extent than in infected T cells.

Notch4 activation aggravates NF-κB-mediated inflammation in HIV-1-associated nephropathy

Disease Models & Mechanisms, 2019
Notch pathway activation plays a central role in the pathogenesis of many glomerular diseases. We have previously shown that Notch4 expression was upregulated in various renal cells in human immunodeficiency virus (HIV)-associated nephropathy (HIVAN ...

Identification of cellular proteins that bind to the human immunodeficiency virus type 1 nef gene product in vitro: a role for myristylation

Journal of General Virology, 1993
The human immunodeficiency virus (HIV) type 1 nef gene product was expressed as an N-terminal fusion protein with glutathione-S-transferase (GST) in the baculovirus system. The resulting nefGST fusion protein was found to be authentically myristylated at the N terminus and could be purified to homogeneity by one-step affinity chromatography on ...

Single‐Nucleus Multiomic Analysis Reveals Immune–Metabolic Reprogramming Consistent With Maladaptive Trained Immunity in HIV‐Associated Neurocognitive Disorders

Glia, Volume 74, Issue 8, August 2026.
Single‐nucleus multiomic profiling of postmortem brain reveals coordinated immune, metabolic, and epigenomic reprogramming in glia of people with HIV consistent with maladaptive trained immunity sustaining neuroinflammation in HAND. ABSTRACT HIV‐associated neurocognitive disorders (HAND) remain prevalent in people with HIV (PWH) despite effective ...

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, Volume 13, Issue 42, 28 July 2026.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

HIV Infection and Opioid Treatment Enable the Engraftment of Kaposi Sarcoma‐Like Tumors Into Immunocompetent Mice

Journal of Medical Virology, Volume 98, Issue 7, July 2026.
ABSTRACT The Kaposi Sarcoma herpesvirus (KSHV) causes Kaposi sarcoma (KS), primary effusion lymphoma, a lymphoproliferative disease (KSHV‐multicentric Castleman's disease), and a cytokine inflammatory syndrome (KICS). These diseases occur more frequently, though not exclusively, among people living with HIV or other types of immune dysregulation. While

CD8+ Tissue‐Resident Memory T Cells in Health and Disease

MedComm, Volume 7, Issue 7, July 2026.
CD8+ TRM cells are at the center of immunity, mediating potent local innate and adaptive immune responses. While TRM cells mediate protective immunity against infections and tumors, they also contribute to pathological inflammation in autoimmune conditions.

Human Coronavirus 229E Uses ORF4/4a to Antagonize the Host Restriction Factor SERINC5

MedComm, Volume 7, Issue 6, June 2026.
The seasonal human coronaviruses 229E and OC43 are common causes of mild respiratory infections but can cause severe disease in vulnerable individuals. Serine incorporator 5 (SERINC5) efficiently inhibits OC43, while hCoV‐229E uses its ORF4/4a accessory proteins to efficiently counteract this restriction by promoting relocalization of SERINC5 to ...
