Crystal Structures of Beta- and Gammaretrovirus Fusion Proteins Reveal a Role for Electrostatic Stapling in Viral Entry [PDF]
ABSTRACT Membrane fusion is a key step in the life cycle of all envelope viruses, but this process is energetically unfavorable; the transmembrane fusion subunit (TM) of the virion-attached glycoprotein actively catalyzes the membrane merger process. Retroviral glycoproteins are the prototypical system to study pH-independent viral entry.

Origin, antiviral function and evidence for positive selection of the gammaretrovirus restriction gene Fv1 in the genus Mus [PDF]
The Fv1 virus resistance gene is a coopted endogenous retrovirus (ERV) sequence related to the gag gene of the MuERV-L ERV family. Three major Fv1 resistance alleles have been identified in laboratory mice, and they target virus capsid genes to produce characteristic ...

Cross-study safety analysis of risk factors in CAR T cell clinical trials: An FDA database pilot project [PDF]
The Chimeric Antigen Receptor (CAR) T Cell Safety Database Project explored the use of cross-study safety data to identify risk factors associated with severe cytokine release syndrome (sCRS) and severe neurological toxicities (sNTX) after CAR T cell ...

Transduction of Nondividing Human Macrophages with Gammaretrovirus-Derived Vectors [PDF]
ABSTRACT It is commonly accepted that infection of nondividing cells by gammaretroviruses such as the murine leukemia viruses is inefficient due to their inability to cross the nuclear envelope barrier. Challenging this notion, we now show that human nondividing macrophages display a specific window of susceptibility to transduction with a ...

Spontaneous Heteromerization of Gammaretrovirus Envelope Proteins: a Possible Novel Mechanism of Retrovirus Restriction [PDF]
ABSTRACT The env gene of gammaretroviruses encodes a glycoprotein conserved among diverse retroviruses, except for the domains involved in receptor binding. Here we show that pairs of gammaretrovirus envelope proteins (from Friend virus and GALV or xenotropic viruses) assemble into heteromers when ...

Ancient invasion of an extinct gammaretrovirus in cetaceans.
Endogenous gammaretroviruses (EGVs) have been widely studied in terrestrial mammals but seldom so in marine species. A genomic mining of the bottlenose dolphin (Tursiops truncatus) genome revealed a new EGV, termed Tursiops truncatus endogenous retrovirus (TTEV), which is divergent from extant mammalian EGVs.

Control of Pathogenicity and Disease Specificity of a T-Lymphomagenic Gammaretrovirus by E-Box Motifs but Not by an Overlapping Glucocorticoid Response Element [PDF]
ABSTRACTAlthough transcription factors of the basic helix-loop-helix family have been shown to regulate enhancers of lymphomagenic gammaretroviruses through E-box motifs, the overlap of an E-box motif (Egre) with the glucocorticoid response element (GRE) has obscured their function in vivo.

Endogenous retroviruses (ERVs) were acquired during evolution of their host organisms after infection and mendelian inheritance in the germline by their exogenous counterparts. The ERVs can spread in the host genome and in some cases they affect the host phenotype. The cervid endogenous gammaretrovirus (CrERV) is one of only a few well-defined examples
