COVID-19 Severity Is Associated with Differential Antibody Fc-Mediated Innate Immune Functions

open access: yesmBio, 2021
A state of hyperinflammation and increased complement activation has been associated with coronavirus disease 2019 (COVID-19) severity. However, the pathophysiological mechanisms that contribute to this phenomenon remain mostly unknown.

The carotid body as a putative therapeutic target for the treatment of neurogenic hypertension [PDF]

open access: yes, 2013
In the spontaneously hypertensive (SH) rat, hyperoxic inactivation of the carotid body (CB) produces a rapid and pronounced fall in both arterial pressure and renal sympathetic nerve activity (RSA).

CTCF driven TERRA transcription facilitates completion of telomere DNA replication

open access: yesNature Communications, 2017
TERRA RNA is involved in maintaining stability during telomere repeat replication. Here the authors, by using CRISPR/Cas9, mutate CTCF-binding sites at start site of TERRA transcripts and find that subtelomeric CTCF facilitates telomeric DNA replication ...

Structural and functional analysis of the human POT1-TPP1 telomeric complex

open access: yesNature Communications, 2017
POT1 and TTP1 are part of the shelterin complex that caps and stabilizes the ends of telomeres. Here the authors present a structural analysis of the human POT1-TTP1 complex, shedding light on how it assembles and how cancer-associated mutations impact ...

Epigenetic specifications of host chromosome docking sites for latent Epstein-Barr virus

open access: yesNature Communications, 2020
Epstein-Barr virus (EBV) episomes tether to the host chromosome via EBNA1. Here, using circular chromosome conformation capture (4C), Kim et al. identify attachment sites and show that EBV episomes preferentially associate with transcriptionally silenced

Telomeres and Viruses: Common Themes of Genome Maintenance

open access: yesFrontiers in Oncology, 2012
Genome maintenance mechanisms actively suppress genetic instability associated with cancer and aging. Some viruses provoke genetic instability by subverting the host’s control of genome maintenance.
