The role of chromatin biology and epigenetics in disease progression is gaining increasing recognition. Genes that escape X chromosome inactivation (XCI) can impact neuroinflammation through epigenetic mechanisms. Our previous study has suggested that the X escapee genes Kdm6a and Kdm5c are involved in microglial activation after stroke in aged mice.

The lifecycle progression of the malaria parasite requires precise tuning of gene expression including histone methylation. The histone methyltransferase SET10 was previously described as an H3K4 methyltransferase involved in gene regulation, making it a prominent antimalarial target. In this study, we investigated the role of SET10 in the blood stages of in more detail, using tagged SET10-knockout (KO) and -knockdown (KD) lines.

Article Synopsis
  • Chromatin biology and epigenetics are increasingly recognized for their roles in disease progression, particularly in neuroinflammation related to genes that escape X chromosome inactivation (XCI).
  • Research indicates that specific genes involved in microglial activation after a stroke in aged mice could be modulating inflammatory responses through these epigenetic mechanisms.
  • The study explores how the demethylation of histones H3K27Me3 and H3K4Me3 affects the transcription of interferon regulatory factors (IRF5 and IRF4), contributing to inflammation and worse outcomes after stroke, highlighting a critical role for IRF5 signaling in this process.

Background: Respiratory syncytial virus (RSV) is one of the major pathogens frequently associated with severe respiratory tract infections in younger children and older adults globally. There is an unmet need with a lack of routine country-specific databases and/or RSV surveillance systems on RSV disease burden among adults in most low- and middle-income countries, including Cameroon. We aim to estimate the adult RSV burden needed to develop a framework for establishing an RSV surveillance database in Cameroon.
