Project description:Innate immune memory, also refered to as trained immunity (TRIM) is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components. In this study we exposed monocytes from healthy donors to uric acid ex vivo, and analyzed the effect of this exposure on gene expression changes. After 'uric acid' or 'media only' treatments, monocytes were exposed to LPS for 4 hours to measure they response to this pyrogen.
Project description:Innate immune memory, also refered to as trained immunity (TRIM) is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components. In this study we exposed monocytes from healthy donors to mevalonate ex vivo, and analyzed the effect of this exposure on gene expression and histone modification changes.
Project description:Innate immune memory is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components such as Beta glucan or the BCG vaccine. Here we characterize the transcriptional events following oxidized low-density lipoprotein (oxLDL) duced trained innate immunity using RNA-seq data.
Project description:Prospective, open labelled, multicenter trial to evaluate the feasibility of ex vivo culture 3D (chemogram obtaining) on biopsies in order to estimate the predictive value of this technique for treatment response in patients treated by two different chemotherapies (FOLFOX or FOLFIRI) for colorectal cancer.
