Effet anti-tumoral de l'acide docosahexaénoïque : implication des microARNs et du TNFalpha
2015
Docosahexaenoic acid (DHA) is an omega-3 polyunsaturated fatty acid with anti-inflammatory and anti-tumoral properties. The anti-tumor effect of DHA in colorectal cancer might be attributed to direct anti-proliferative action on cancer cells and to its ability to reduce inflammatory status involved in tumor growth. Tumor Necrosis Factor-alpha (TNFa) is an inflammatory cytokine with paradoxical effect in cancer biology. According to the cellular context, TNFa activates RIP1 kinase dependent signaling pathway leading to proliferation or cell death. Our aim was to evaluate the role of TNFa in anti-proliferative effect of DHA in colon cancer cells and to precise the molecular mechanisms regulat…
Interleukin 10 restores lipopolysaccharide-induced alterations in synaptic plasticity probed by repetitive magnetic stimulation
2020
Systemic inflammation is associated with alterations in complex brain functions such as learning and memory. However, diagnostic approaches to functionally assess and quantify inflammation-associated alterations in synaptic plasticity are not well-established. In previous work, we demonstrated that bacterial lipopolysaccharide (LPS)-induced systemic inflammation alters the ability of hippocampal neurons to express synaptic plasticity, i.e., the long-term potentiation (LTP) of excitatory neurotransmission. Here, we tested whether synaptic plasticity induced by repetitive magnetic stimulation (rMS), a non-invasive brain stimulation technique used in clinical practice, is affected by LPS-induc…
