Primate lentiviruses use at least three alternative strategies to suppress NF-κB-mediated immune activation.

PLoS Pathogens, 2017
Primate lentiviruses have evolved sophisticated strategies to suppress the immune response of their host species. For example, HIV-2 and most simian immunodeficiency viruses (SIVs) use their accessory protein Nef to prevent T cell activation and ...

Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

Advanced Science, Volume 13, Issue 38, 9 July 2026.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

Evidence for Adaptive Evolution at the Divergence Between Lymphoid and Brain HIV-1 nef Genes [PDF]

AIDS Research and Human Retroviruses, 2010
Human immunodeficiency virus type 1 (HIV) infection of the central nervous system frequently causes HIV-associated neurocognitive disorders (HAND). The role of HIV Nef and other accessory proteins in HAND pathogenesis is unclear. To determine whether HIV nef undergoes adaptive selection in ...

Persistence of attenuated HIV-1 rev alleles in an epidemiologically linked cohort of long-term survivors infected with nef-deleted virus

Retrovirology, 2007
Background The Sydney blood bank cohort (SBBC) of long-term survivors consists of multiple individuals infected with nef-deleted, attenuated strains of human immunodeficiency virus type 1 (HIV-1).

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

Modulation in the Gene Expression Profile of Astrocytes and Monocytes by HIV-1 Nef Variants

, 2022
HIV-1 Nef is a multifunctional protein with well-known lethal properties. HIV infects various cells from the brain compartment and expressed nef is responsible for developing neuropathogenic potential. HIV-infected glial cells express nefvirotoxinand stimulate the cascade of various pathways to activate uninfected cells to release neurotoxic elements ...

Optimal infectivity in vitro of human immunodeficiency virus type 1 requires an intact nef gene [PDF]

Journal of Virology, 1994
The replication competence of human immunodeficiency virus type 1 genomes containing mutations in the nef open reading frame was evaluated in continuous cell lines. Mutants that contained a deletion in the nef open reading frame, premature termination codons, or missense mutations in the N-terminal myristoylation signal were constructed.

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.

Host restriction factors in retroviral infection: promises in virus-host interaction

Retrovirology, 2012
Retroviruses have an intricate life cycle. There is much to be learned from studying retrovirus-host interactions. Among retroviruses, the primate lentiviruses have one of the more complex genome structures with three categories of viral genes ...

Antiviral regulator TRIM25 as a prognostic marker of better survival in Merkel cell carcinoma: Association with MCPyV status

International Journal of Cancer, Volume 158, Issue 12, Page 3268-3278, 15 June 2026.
What's new? TRIM25 is known for its role in antiviral immunity and association with poor prognosis in various cancers. This study reveals an association between high TRIM25 expression and Merkel cell polyomavirus positivity in Merkel cell carcinoma.
