Tradeoffs in viral fitness driven by alternative entry pathways
mBioEnveloped viruses can enter cells either through endocytosis or by direct fusion with the plasma membrane. The latter pathway often leads to syncytia formation, caused by the fusion of infected cells with neighboring receptor-bearing cells.

BST2/Tetherin enhances entry of human cytomegalovirus.
PLoS Pathogens, 2011 Interferon-induced BST2/Tetherin prevents budding of vpu-deficient HIV-1 by tethering mature viral particles to the plasma membrane. BST2 also inhibits release of other enveloped viruses including Ebola virus and Kaposi's sarcoma associated herpesvirus ...

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Unlocking the potential of cell‐permeable nanobodies for intracellular applications
FEBS Letters, EarlyView.This review outlines current strategies for delivery of nanobodies into cells and highlights recent examples of functional applications. By addressing and manipulating intracellular targets, these molecules hold great potential for treating cancer, respiratory diseases and neurological disorders, making this a vibrant area of research in the biomedical

Critical amino acid residues in human ACE2 for SARS-CoV-2 spike protein binding and virus entry
Microbiology SpectrumThe coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), remains a significant global public health concern due to the continuous emergence and rapid spread of new variants.

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Role of CD4 epitopes outside the gp120-binding site during entry of human immunodeficiency virus type 1 [PDF]
, 1997 CD4 is the primary receptor for human immunodeficiency virus (HIV). The binding site for the surface glycoprotein of HIV type 1 (HIV-1), gp120, has been mapped to the C'-C" region of domain 1 of CD4. Previously, we have shown that a mutant of rat CD4, in
