Intact olfaction in a mouse model of multiple system atrophy. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Increasing evidence suggests that olfaction is largely preserved in multiple system atrophy while most patients with Parkinson's disease are hyposmic.

Melatonin in the mammalian olfactory bulb [PDF]

open access: yesNeuroscience, 2014
Melatonin is a neurohormone associated with circadian rhythms. A diurnal rhythm in olfactory sensitivity has been previously reported and melatonin receptor mRNAs have been observed in the olfactory bulb, but the effects of melatonin in the olfactory bulb have not been explored.

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

open access: yesAdvanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Tryptophan-5-HT pathway disorder was uncovered in the olfactory bulb of a depression mice model by metabolomic analysis

open access: yesFrontiers in Molecular Neuroscience, 2022
Major depression (MD) is a severe mental illness that creates a heavy social burden, and the potential molecular mechanisms remain largely unknown. Lots of research demonstrate that the olfactory bulb is associated with MD.

Broadcasting of cortical activity to the olfactory bulb

open access: yesCell Reports, 2015
Summary Odor representations are initially formed in the olfactory bulb, which contains a topographic glomerular map of odor molecular features. The bulb transmits sensory information directly to piriform cortex where it is encoded by distributed ...

Non-neuronal expression of SARS-CoV-2 entry genes in the olfactory system suggests mechanisms underlying COVID-19-associated anosmia

open access: yesScience Advances, 2020
: Altered olfactory function is a common symptom of COVID-19, but its etiology is unknown. A key question is whether SARS-CoV-2 (CoV-2) – the causal agent in COVID-19 – affects olfaction directly, by infecting olfactory sensory neurons or their targets ...

Locus coeruleus stimulation modulates olfactory bulb evoked potentials [PDF]

open access: yes, 1987
Field-evoked potentials from the main olfactory bulb in response to stimulation of the olfactory nerve and lateral olfactory tract were measured without and with conditioning stimulation of the locus coeruleus noradrenergic system.

AI‐Designed TREM1‐Targeted LYTAC Nanoparticles Reprogram the Neuroimmune Microenvironment in Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
AI‐enabled de novo design of a TREM1 binder, integrated into a BBB‐crossing and macrophage‐targeted nanoplatform, enables TREM1 degradation and attenuates neuroinflammation, thereby promoting neuroprotection and tissue repair after traumatic brain injury. ABSTRACT Secondary neuroinflammation drives progressive damage after traumatic brain injury (TBI),

PBRM1 Deficiency in Microglia Leads to Excessive Neurogenesis and Autism‐Like Behaviors via the CCL5‐CCR1/5‐β‐catenin Signaling Axis

open access: yesAdvanced Science, EarlyView.
Microglial PBRM1 deficiency drives excessive hippocampal neurogenesis by enhancing CCL5–CCR1/5 signaling, leading to autism‐like behaviors. A pro‐inflammatory IL1α+/TNFα+ microglial subset is identified as a key cellular contributor to this process. PBRM1 represses Ccl5 expression at the transcriptional level.

Flexible Integration of Structurally Diverse Spatial Multi‐Omics With AgaeSMO

open access: yesAdvanced Science, EarlyView.
AgaeSMO is a versatile and robust deep learning framework for flexible cross‐integration of spatial multi‐omics data. Leveraging a GATs network with a graph attention module, it learns joint embedding across diverse modalities, enabling integration of both structurally paired (e.g., spatial transcriptome‐epigenome, transcriptome‐proteome, transcriptome‐
