Mice deficient in classical major histocompatibility complex class I (MHCI) have aberrations in neurodevelopment. The consequences of upregulated neuronal MHCI expression have not been examined. We found that transgenic C57Bl/6 mice that are engineered to express higher levels of self-D(b) on their CNS neurons have alterations in their hippocampal morphology and retinogeniculate projections, as well as impaired neurorepair responses. Thus, enhanced neuronal classical MHCI expression can lead to aberrations in neural circuitry and neurorepair. These findings complement a growing body of knowledge concerning the neurobiological activities of MHCI and may have potential clinical relevance.

Alzheimer's Disease (AD) constitutes approximately 70 % of dementia cases and is the most prevalent form of dementia. Current therapeutic options, including acetylcholinesterase inhibitors and N-methyl d-aspartate (NMDA) receptor antagonists, provide symptomatic relief but do not cure the disease and often come with side effects. The primary pathological features of AD are amyloid plaques and neurofibrillary tangles, with amyloid plaques formed by the abnormal accumulation of Amyloid-β (Aβ).

Ethnopharmacological Relevancy: Lancao decoction (LC) is a traditional Chinese medicine (TCM) formulation mentioned in the "Huangdineijing", known for its ability to dispel turbidity and eliminate heat. TCM believes that the etiology of Alzheimer's disease (AD) is phlegm turbidity, and the fiery internal obstruction of the gods, which suggests that LC has the possibility of treating.
Aim Of The Study: This investigation will examine the possibilities of LC to improve AD and uncover the underlying mechanisms.

Tau protein accumulation is linked to dementia progression in Alzheimer's disease (AD), with potential co-pathologies contributing to it. The progression of dementia in AD patients varies between individuals, and the association between co-pathology and heterogeneity in dementia progression rate remains unclear. We used longitudinal cohort data, postmortem brain tissues, and biochemical methods such as immunoassays and proteomic profiling to investigate the molecular components associated with progression rate.

Nicotine enhances recognition memory across species; however, the underlying neuronal mechanisms remain incompletely understood. Our previous study using a novel object recognition (NOR) test and electrophysiological recordings of mouse brain slices demonstrated that nicotine enhanced object recognition memory by stimulating nicotinic acetylcholine receptors in the medial prefrontal cortex (mPFC). To elucidate this further, we conducted the NOR test combined with pharmacology, chemogenetics, optogenetics, and ex vivo electrophysiology in male C57BL/6J mice.

Objective: This study aimed to assess the effects of focal brain cooling (FBC) on human brain tissue through use of multiple sensing techniques by monitoring cerebrovascular activity and brain temperature.
Methods: Intraoperative brain activity monitoring using a multimodality probe capable of measuring brain temperature, electrocorticography (ECoG) and changes in cerebral hemoglobin concentration was performed in 13 patients with refractory epilepsy. Brain temperature and neurovascular activity were measured beneath and surrounding the FBC device.
