A Comparison of the Innate and Adaptive Immune Systems in Cartilaginous Fish, Ray-Finned Fish, and Lobe-Finned Fish

open access: yesFrontiers in Immunology, 2019
The immune system is composed of two subsystems—the innate immune system and the adaptive immune system. The innate immune system is the first to respond to pathogens and does not retain memory of previous responses.

Defective apoptotic cell clearance activates innate immune response to protect Caenorhabditis elegans against pathogenic bacteria

open access: yesVirulence, 2021
Appropriate clearance of dead cells generated by apoptosis is critical to the development of multicellular organisms and tissue homeostasis. In mammals, the removal of apoptotic cell is mediated by polarized monocyte/macrophage populations of the innate ...

Die Kämpfe únd schláchten—the struggles and battles of innate-like effector T lymphocytes with microbes

open access: yesFrontiers in Immunology, 2023
The large majority of lymphocytes belong to the adaptive immune system, which are made up of B2 B cells and the αβ T cells; these are the effectors in an adaptive immune response.

Four Pathways Involving Innate Immunity in the Pathogenesis of Preeclampsia

open access: yesFrontiers in Cardiovascular Medicine, 2015

The roles of extracellular vesicles in the immune system

open access: yesNature reviews. Immunology, 2022
Extracellular vesicles (EVs) are increasingly recognized as having ubiquitous roles in the immune system. This Review focuses on the progress made in the field in the past 5 years, including the roles of EVs in innate and adaptive immunity and their ...

Interaction between Cannabinoid System and Toll-Like Receptors Controls Inflammation

open access: yesMediators of Inflammation, 2016
Since the discovery of the endocannabinoid system consisting of cannabinoid receptors, endogenous ligands, and biosynthetic and metabolizing enzymes, interest has been renewed in investigating the promise of cannabinoids as therapeutic agents.

Memory and Specificity in the Insect Immune System: Current Perspectives and Future Challenges

open access: yesFrontiers in Immunology, 2017
The immune response of a host to a pathogen is typically described as either innate or adaptive. The innate form of the immune response is conserved across all organisms, including insects.

Bacteriophage and the Innate Immune System: Access and Signaling

open access: yesMicroorganisms, 2019
Bacteriophage and the bacteria they infect are the dominant members of the gastrointestinal microbiome. While bacteria are known to be central to maintenance of the structure, function, and health of the microbiome, it has only recently been recognized ...

Regulation of short-chain fatty acids in the immune system

open access: yesFrontiers in Immunology, 2023
A growing body of research suggests that short-chain fatty acids (SCFAs), metabolites produced by intestinal symbiotic bacteria that ferment dietary fibers (DFs), play a crucial role in the health status of symbiotes. SCFAs act on a variety of cell types

Long‐term reprogramming of the innate immune system

open access: yesJournal of Leukocyte Biology, 2018
During the last few years, a growing body of evidence has shown that immunological memory is not an exclusive trait of lymphocytes, as many inflammatory insults can alter the functionality and the responsiveness of the innate immune system in the long ...
