Detection of antibody-dependent complement mediated inactivation of both autologous and heterologous virus in primary HIV-1 infection [PDF]

, 2005
Specific CD8 T-cell responses to human immunodeficiency virus type 1 (HIV-1) are induced in primary infection and make an important contribution to the control of early viral replication.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Influenza Virus-cell Fusion Inhibition Assay

Bio-Protocol, 2013
During viral infection to host cells, several viruses undergo the process of endocytosis and pH-dependent fusion. By fusion of viral membrane with host cellular membrane, the viral core invades to host cytoplasm.

Antibody Neutralization of HIV-1 Crossing the Blood-Brain Barrier

mBio, 2020
HIV-1 can cross the blood-brain barrier (BBB) to penetrate the brain and infect target cells, causing neurocognitive disorders as a result of neuroinflammation and brain damage.

Epidemiological evidence of acute transmission of Zika virus infection in dengue suspected patients in Sri-Lanka

Journal of Infection and Public Health, 2023
Background: Zika Virus (ZIKV) is a re-emerging, arthropod-borne flavivirus transmitted by Aedes mosquitoes (Ae. aegypti and Ae. albopictus). The coexistence of dengue virus (DENV) and ZIKV concurrently has been associated with a wide array of ...

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Potent SARS-CoV-2 neutralizing antibodies with therapeutic effects in two animal models

iScience, 2022
Summary: The use of therapeutic neutralizing antibodies against SARS-CoV-2 infection has been highly effective. However, there remain few practical antibodies against viruses that are acquiring mutations.

Viral interference with antibody and complement

Seminars in Cell & Developmental Biology, 1998
Viruses have evolved strategies to evade immunity mediated by antibody and complement. Herpesviruses and coronaviruses encode IgG Fc binding proteins that inhibit IgG activity, enabling the virus or infected cell to escape antibody attack. Herpesviruses, vaccinia virus and HIV-1 have the capacity to interfere with complement, either by incorporation of
