Adrenergic signaling dampens T cell activity during chronic infection and cancer
Trends Neurosci. 2023 Dec 20:S0166-2236(23)00274-6. doi: 10.1016/j.tins.2023.12.001. Online ahead of print.ABSTRACTStress contributes to infection and cancer susceptibility, but the mediating mechanisms are still being elucidated. CD8 T cells are critical players in antiviral and antitumor immune responses. A recent study by Globig et al., together with a growing body of literature, link norepinephrine produced during the stress response to CD8 T cell dysfunction.PMID:38129194 | DOI:10.1016/j.tins.2023.12.001 (Source: Trends in Neurosciences)

Complement-mediated synapse loss in Alzheimer's disease: mechanisms and involvement of risk factors
Trends Neurosci. 2023 Dec 20:S0166-2236(23)00272-2. doi: 10.1016/j.tins.2023.11.010. Online ahead of print.ABSTRACTThe complement system is increasingly recognized as a key player in the synapse loss and cognitive impairments observed in Alzheimer's disease (AD). In particular, the process of complement-dependent synaptic pruning through phagocytosis is over-activated in AD brains, driving detrimental excessive synapse elimination and contributing to synapse loss, which is the strongest neurobiological correlate of cognitive impairments in AD. Herein we review recent advances in characterizing complement-mediated synapse l...

Toward identifying key mechanisms of progression in multiple sclerosis
Trends Neurosci. 2023 Dec 14:S0166-2236(23)00265-5. doi: 10.1016/j.tins.2023.11.005. Online ahead of print.ABSTRACTA major therapeutic goal in the treatment of multiple sclerosis (MS) is to prevent the accumulation of disability over an often decades-long disease course. Disability progression can result from acute relapses as well as from CNS intrinsic parenchymal disintegration without de novo CNS lesion formation. Research focus has shifted to progression not associated with acute inflammation, as it is not sufficiently controlled by currently available treatments. This review outlines how recent advances in the underst...

The locus coeruleus as a global model failure system
Trends Neurosci. 2023 Dec 14:S0166-2236(23)00268-0. doi: 10.1016/j.tins.2023.11.006. Online ahead of print.ABSTRACTPredictive processing models posit that brains constantly attempt to predict their sensory inputs. Prediction errors signal when these predictions are incorrect and are thought to be instructive signals that drive corrective plasticity. Recent findings support the idea that the locus coeruleus (LC) - a brain-wide neuromodulatory system - signals several types of prediction error. I discuss how these findings support models proposing that the LC signals global model failures: instances where predictions about t...

Ontogeny of the circadian system: a multiscale process throughout development
Trends Neurosci. 2023 Dec 8:S0166-2236(23)00264-3. doi: 10.1016/j.tins.2023.11.004. Online ahead of print.ABSTRACTThe 24 h (circadian) timing system develops in mammals during the perinatal period. It carries out the essential task of anticipating daily recurring environmental changes to identify the best time of day for each molecular, cellular, and systemic process. Although significant knowledge has been acquired about the organization and function of the adult circadian system, relatively little is known about its ontogeny. During the perinatal period, the circadian system progressively gains functionality under the in...
