Journal ArticleDOI
Recognition of microorganisms and activation of the immune response.
TL;DR: The mammalian immune system has innate and adaptive components, which cooperate to protect the host against microbial infections, and recent progress brings us closer to an integrated view of the immune system and its function in host defence.
Journal ArticleDOI
A cytokine-mediated link between innate immunity, inflammation, and cancer
Wan-Wan Lin,Michael Karin +1 more
TL;DR: An overview of the current understanding of the role of inflammation-induced cytokines in tumor initiation, promotion, and progression is provided.
Journal ArticleDOI
Intracellular pattern recognition receptors in the host response
TL;DR: It is apparent that Toll-like receptors, a class of membrane receptors that sense extracellular microbes and trigger anti-pathogen signalling cascades, are likely to have critical roles in health and disease.
Journal ArticleDOI
Innate immunity gone awry : linking microbial infections to chronic inflammation and cancer
TL;DR: How alteration of innate immune response genes in murine models can provide insights into the potential microbial origins of diverse conditions including Crohn's disease, psoriasis, atherosclerosis, diabetes, and liver cancer is reviewed.
Journal ArticleDOI
Signaling Pathways Downstream of Pattern-Recognition Receptors and Their Cross Talk
Myeong Sup Lee,Young Joon Kim +1 more
TL;DR: Signaling pathways downstream of PRRs and their cross talk control immune responses in effective manners and can be negatively regulated by negative feedback mechanisms and also by anti-inflammatory factors such as TGFbeta, interleukin (IL)-10, and steroids.

TL;DR: It is suggested that the NOD2 gene product confers susceptibility to Crohn's disease by altering the recognition of these components and/or by over-activating NF-kB in monocytes, thus documenting a molecular model for the pathogenic mechanism of Crohn’s disease that can now be further investigated.

A frameshift mutation in NOD2 associated with susceptibility to Crohn's disease
Yasunori Ogura,Denise K. Bonen,Naohiro Inohara,Dan L. Nicolae,Felicia F. Chen,Richard Ramos,Heidi M. Britton,Thomas M. Moran,Reda Karaliuskas,Richard H. Duerr,Jean-Paul Achkar,Steven R. Brant,Theodore M. Bayless,Barbara S. Kirschner,Stephen B. Hanauer,Gabriel Núñez,Judy H. Cho +16 more
TL;DR: It is shown that a frameshift mutation caused by a cytosine insertion, 3020insC, which is expected to encode a truncated NOD2 protein, is associated with Crohn's disease, and a link between an innate immune response to bacterial components and development of disease is suggested.

Recognition of Commensal Microflora by Toll-Like Receptors Is Required for Intestinal Homeostasis
Seth Rakoff-Nahoum,Justin C. Paglino,Fatima Eslami-Varzaneh,Stephen C. Edberg,Ruslan Medzhitov +4 more
TL;DR: It is shown that commensal bacteria are recognized by TLRs under normal steady-state conditions, and this interaction plays a crucial role in the maintenance of intestinal epithelial homeostasis and protection from injury.
Journal ArticleDOI
NF-κB at the crossroads of life and death
Michael Karin,Anning Lin +1 more
TL;DR: The choice between life and death is one of the major events in regulation of the immune system and a major regulator of such life or death decisions is the transcription factor NF-κB as mentioned in this paper.
Journal ArticleDOI
Nod2 is a general sensor of peptidoglycan through muramyl dipeptide (MDP) detection.
Stephen E. Girardin,Ivo G. Boneca,Jérôme Viala,Mathias Chamaillard,Agnès Labigne,Gilles Thomas,Dana J. Philpott,Philippe J. Sansonetti +7 more
TL;DR: It is shown here that Nod2 is a general sensor of peptidoglycan through the recognition of muramyl dipeptide (MDP), the minimal bioactive peptIDoglycan motif common to all bacteria.
