AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Dentritic cells (DC) are the most potent antigen-presenting cells and play a key role in the induction of effective immune responses, suggesting a novel target for anti-tumor immunotherapy. Paclitaxel (PXL) is a widely used chemotherapeutic, initially char ...
L. monocytogenes is a Gram-positive intracellular pathogen that can cause serious disease, like septicemia and meningitis. It is detected in the cytosol by the innate immune system by sensing pathogen ligands. c-di-AMP has recently been shown to be one of ...
Hyperplasia associated with a loss of tissue homeostasis can induce DNA replication stress, leading to precancerous dysregulation. Epidermal {gamma}{delta} T cells reside in the primary barrier that protects against diverse environmental insults; however, ...
The Jacques Monod conference "Insect Immunity in Action: From Fundamental Mechanisms of Host Defense to Resistance Against Infections in Nature," organized by Ulrich Theopold (Stockholm University, Sweden) and Dominique Ferrandon (CNRS, France), was held i ...
Lymphocytes are a key component of the immune system and their differentiation and function are directly influenced by cancer. We examined peripheral blood lymphocyte (PBL) gene expression as a biomarker of illness and treatment effect using the Affymetrix ...
Peptidoglycan recognition proteins (PGRPs) are key regulators of insect immune responses. In addition to recognition PGRPs, which activate the Toll and Imd pathways, the Drosophila genome encodes six catalytic PGRPs with the capacity to scavenge peptidogly ...
Interferon (IFN) is effective at inducing complete remissions in patients with chronic myelogenous leukemia (CML), and evidence supports an immune mechanism. Here we show that the type I IFNs (alpha and beta) regulate expression of the IFN consensus sequen ...
Understanding how human genetic variation impacts individual response to immunogens is fundamental for rational vaccine development. To explore host mechanisms involved in cellular immune responses to the MRKAd5 human immunodeficiency virus type 1 (HIV-1) ...
Stringent control of immune responses in the intestinal mucosa is critical for the maintenance of immune homeostasis and prevention of tissue damage, such as observed during inflammatory bowel disease. Intestinal epithelial cells, primarily thought to form ...
This chapter discusses the mechanisms whereby Drosophila recognize foreign microbes, the signalling systems that regulate adapted responses against them, and the effector mechanisms used to control them. It first focuses on the so-called systemic antimicro ...
