Multitasking: Making the Most out of the Retroviral Envelope
Viruses, 2010 Evasion of the host’s immune system is a required step for the establishment of viral infection. In this article, we discuss the recent findings of Heidmann and colleagues demonstrating that some retroviruses possess an immune suppressive (IS) domain ...

The Interplay between HIV-1 Gag Binding to the Plasma Membrane and Env Incorporation
Viruses, 2020 Advancement in drug therapies and patient care have drastically improved the mortality rates of HIV-1 infected individuals. Many of these therapies were developed or improved upon by using structure-based techniques, which underscore the importance of ...

Mass-Radius Relations and Core-Envelope Decompositions of Super-Earths and Sub-Neptunes
, 2014 Many exoplanets have been discovered with radii of 1-4 Earth radii, between that of Earth and Neptune. A number of these are known to have densities consistent with solid compositions, while others are "sub-Neptunes" likely to have significant hydrogen ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

The HIV Env Glycoprotein Conformational States on Cells and Viruses
mBio, 2022 The HIV Env glycoprotein is the surface glycoprotein responsible for viral entry into CD4+ immune cells. During infection, Env also serves as a primary target for antibody responses, which are robust but unable to control virus replication.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Journal of Mathematical Analysis and Applications, 1993 Denote by \textbf{B} a Boolean algebra and by \(P\) the set of finitely additive probabilities in \textbf{B}. We call an initial valuation any map \(v\) from \textbf{B} in \([0,1]\); the meaning of \(v\) is that the available information about a random phenomenon is of type ``the actual probability of the event \(e\) is at least \(v(e)\)''.

Plurisubharmonicity of envelopes of disc functionals on manifolds
, 2002 We show that a disc functional on a complex manifold has a plurisubharmonic envelope if all its pullbacks by holomorphic submersions from domains of holomorphy in affine space do and it is locally bounded above and upper semicontinuous in a certain weak ...

Difference in response reliability predicted by STRFs in the cochlear nuclei of barn owls [PDF]
, 2011 The brainstem auditory pathway is obligatory for all aural information. Brainstem auditory neurons must encode the level and timing of sounds, as well as their time-dependent spectral properties, the fine structure and envelope, which are essential for ...
