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.

Metabolomic Profiling Reveals Distinct and Mutual Effects of Diet and Inflammation in Shaping Systemic Metabolism in Ldlr^−/− Mice

Metabolites, 2020
Changes in modern dietary habits such as consumption of Western-type diets affect physiology on several levels, including metabolism and inflammation. It is currently unclear whether changes in systemic metabolism due to dietary interventions are long ...

Mosquito Innate Immunity [PDF]

Insects, 2018
Mosquitoes live under the endless threat of infections from different kinds of pathogens such as bacteria, parasites, and viruses. The mosquito defends itself by employing both physical and physiological barriers that resist the entry of the pathogen and the subsequent establishment of the pathogen within the mosquito.

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 ...

Aging and Innate Immunity [PDF]

Immunity, 2006
Adaptive immunity undergoes severe deterioration with age and represents the main problem in the elderly. However, evidence accumulated over the last decade supports the hypothesis that aging also has a profound impact on innate immunity, which in turn markedly impacts the health and longevity of older people.

Prevention of Diabetes-Associated Cognitive Dysfunction Through Oral Administration of Lipopolysaccharide Derived From Pantoea agglomerans

Frontiers in Immunology, 2021
Diabetes-related cognitive dysfunction (DRCD) is a serious complication induced by diabetes. However, there are currently no specific remedies for DRCD. Here, we show that streptozotocin-induced DRCD can be prevented without causing side effects through ...

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.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

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.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

FEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
