Parkinson's disease (PD), a neurodegenerative disorder without cure, is characterized by the pathological aggregation of α-synuclein (α-Syn) in Lewy bodies. Classic deposition pathway and condensation pathway contribute to α-Syn aggregation, and liquid-liquid phase separation is the driving force for condensate formation, which subsequently undergo liquid-solid phase separation to form toxic fibrils. Traditional Chinese Medicine (TCM) has a long history in treating neurodegenerative disease; herein, we identified chemicals from herbs that inhibit α-Syn aggregation.

Nociplastic pain among individuals with chronic ocular surface pain: One cause for "pain without stain"?

Surv Ophthalmol

January 2025

Michigan Medicine, Department of Ophthalmology and Visual Sciences, Ann Arbor, MI, USA.

Chronic ocular surface pain (COSP) refers to interrelated symptoms such as burning, aching, and irritation and can occur as an isolated condition or comorbid with numerous ocular disorders, including dry eye syndrome Treatments for COSP are largely aimed at the ocular surface and modulating pain arising from damaged corneal nerves; however, the average impact of these treatments on COSP are low to absent. A potential explanation for this is that, in a subset of patients with COSP, individuals have amplified and/or dysregulated neural signaling and sensory processing within the central nervous system (CNS). As in other chronic pain conditions, this might be the pathogenic mechanism primarily responsible for maintaining pain - a phenomenon now referred to as nociplastic pain.

Identifying genetic differences between bipolar disorder and major depression through multiple genome-wide association analyses.

Br J Psychiatry

January 2025

Center for Neurobehavioral Genetics, Semel Institute for Neuroscience and Human Behavior, David Geffen School of Medicine, University of California Los Angeles, USA; Department of Human Genetics, University of California Los Angeles, USA; and Department of Computational Medicine, University of California Los Angeles, USA.

Background: Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).

Aims: We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.

Berardinelli-Seip congenital lipodystrophy (BSCL), also known as congenital generalized lipodystrophy (CGL), is an exceptionally rare autosomal recessive disorder marked by a significant deficiency of adipose tissue throughout the body. This lack of adipose tissue, normally found beneath the skin and between internal organs, leads to impaired adipocyte formation and fat storage, causing lipids to accumulate in atypical tissues such as muscles and the liver. The extent of adipose tissue loss directly influences the severity of symptoms, which can include a muscular appearance, increased appetite, bone cysts, marrow fat depletion, acromegalic features, severe insulin resistance, skeletal muscle hypertrophy, hypertrophic cardiomyopathy, hepatic steatosis, hepatomegaly, cirrhosis, and intellectual disability.

Background: Venetoclax + azacitidine is a frontline treatment for older adult acute myeloid leukemia (AML) patients and a salvage therapy for relapsed/refractory patients who have been treated with intensive chemotherapy. While this is an important treatment option, many patients fail to achieve complete remission and of those that do, majority relapse. Leukemia stem cells (LSCs) are believed to be responsible for AML relapse and can be targeted through oxidative phosphorylation reduction.

Stereo-seq of the prefrontal cortex in aging and Alzheimer's disease.

Nat Commun

January 2025

Tulane Center for Biomedical Informatics and Genomics, Deming Department of Medicine, School of Medicine, Tulane University, New Orleans, LA, 70112, USA.

Aging increases the risk for Alzheimer's disease (AD), driving pathological changes like amyloid-β (Aβ) buildup, inflammation, and oxidative stress, especially in the prefrontal cortex (PFC). We present the first subcellular-resolution spatial transcriptome atlas of the human prefrontal cortex (PFC), generated with Stereo-seq from six male AD cases at varying neuropathological stages and six age-matched male controls. Our analyses revealed distinct transcriptional alterations across PFC layers, highlighted disruptions in laminar structure, and exposed AD-related shifts in layer-to-layer and cell-cell interactions.

As the aging population continues to grow, the incidence of osteoporotic fractures increases and is compounded by our lack of therapeutic strategies that increase bone formation. Although exercise and physical activity play a key role in maintaining bone mass throughout our lives, the loads and exertion required to elicit an anabolic response becomes exceedingly difficult to achieve with age. Based on previous work, the P2Y receptor offers a unique therapeutic target to increasing bone mass by modifying the mechanotransduction.
