Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Micronutrients and Innate Immunity [PDF]
The Journal of Infectious Diseases, 2000 Micronutrients such as zinc, selenium, iron, copper, beta-carotene, vitamins A, C, and E, and folic acid can influence several components of innate immunity. Select micronutrients play an important role in alteration of oxidant-mediated tissue injury, and phagocytic cells produce reactive oxidants as part of the defense against infectious agents. Thus,

Nature CommunicationsInflammasome activation results in the cleavage of gasdermin D (GSDMD) by pro-inflammatory caspases. The N-terminal domains (GSDMDNT) oligomerize and assemble pores penetrating the target membrane.

Nature Communications, 2022 Innate lymphoid cells (ILC) are effector cells that rapidly respond to immune evading stimuli, and despite their functional diversity arise from common precursors.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Gasdermin E deficiency limits inflammation and lung damage during influenza virus infection
Cell Death and DiseaseSevere influenza A virus (IAV) infections are associated with hyperinflammation and significant lung damage. Gasdermin E (GSDME) mediates pyroptosis, a lytic and inflammatory type of cell death.

RIG-I-like receptors direct inflammatory macrophage polarization against West Nile virus infection
Nature Communications, 2019 RIG-I- like receptors (RLRs) play an important role in immune defense against West Nile virus (WNV). Here, using a systems biology approach, the authors show that macrophage polarization to a proinflammatory M1 phenotype via RIG-I and MDA5 signaling is ...

mBio, 2023 Influenza A virus (IAV) triggers multiple programmed cell death pathways, including MLKL-dependent necroptosis, caspase-8-dependent apoptosis, and caspase-1-dependent pyroptosis in myeloid cells.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Innate immunity and coagulation [PDF]
Journal of Thrombosis and Haemostasis, 2011 Infection frequently elicits a coagulation response. Endotoxin triggers the formation of tissue factor initiating coagulation, down regulates anticoagulant mechanisms including the protein C pathway and heparin-like proteoglycans and up regulates plasminogen activator inhibitor. The overall physiological result of this is to promote coagulation through
