Innate Immunity in Disease [PDF]

Clinical Gastroenterology and Hepatology, 2014
Cells can innately recognize generic products of viruses, bacteria, fungi, or injured tissue by engagement of pattern recognition receptors. Innate immune cells rapidly respond to this engagement to control commensals, thwart pathogens, and/or prompt repair. Insufficient or excessive activation of the innate immune response results in disease.

Baseline data collections of lipopolysaccharide content in 414 herbal extracts and its role in innate immune activation

Scientific Reports
Some herbal extracts contain relatively high amounts of lipopolysaccharide (LPS). Because orally administered LPS activates innate immunity without inducing inflammation, it plays a role as an active ingredient in herbal extracts.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

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,

Antagonistic nanobodies implicate mechanism of GSDMD pore formation and potential therapeutic application

Nature Communications
Inflammasome 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.

Notch, RORC and IL-23 signals cooperate to promote multi-lineage human innate lymphoid cell differentiation

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.

MLKL-Driven Inflammasome Activation and Caspase-8 Mediate Inflammatory Cell Death in Influenza A Virus Infection

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.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

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 ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
