Understanding host factors driving asymptomatic versus severe disease outcomes is of key importance if we are to control emerging and re-emerging viral infections. HLA-B*15:01 has been associated with asymptomatic SARS-CoV-2 infection in nonhospitalized individuals of European ancestry, with protective immunity attributed to preexisting cross-reactive CD8 T-cells directed against HLA-B*15:01-restricted Spike-derived S peptide (B15/SCD8 T-cells). However, fundamental questions remained on the abundance and clonotypic nature of CD8 T-cell responses in HLA-B*15:01-positive patients who succumbed to life-threatening COVID-19.

Background: Recent studies suggest that the diabetes might be associated with higher risk for primary open angle glaucoma (POAG) and Alzheimer's disease (AD). However, studies have not addressed the critical issue of confounding by indication, and associations have not been evaluated in a large cross-sectional study. We started this cross-sectional study included United Kingdom Biobank (UKBB) participants with complete data (2006-2010) for analysis to explore the associations between diabetes mellitus (DM) and POAG and AD by considering depression and diabetic retinopathy (DR) as intermediate factors.

Genetic investigation in Mendelian skin disorders featuring generalized or localized skin scaling and redness, known as the ichthyoses, has revealed novel pathways relevant to epidermal integrity, barrier function, and desquamation. Here, we show that a recurrent de novo missense variant in (epithelial membrane protein 2), which encodes a cell surface tetraspan protein in the growth-arrest specific 3 (GAS3)/peripheral myelin protein 22 (PMP22) family, is associated with a Mendelian skin disorder in the progressive symmetric erythrokeratoderma spectrum. The disorder features severely thickened, red, and scaly skin at sites of wound healing or repetitive movement including on the face, genitals, flexural areas, and the palms and soles.

Zine-making can facilitate our remembering of origin stories and experiential knowledge around our differential racializations within coloniality; it can illuminate who we are in relation to systemic racism and power and, importantly, how we might work toward liberatory futures for self and community. In this article, we describe how psychology can be transformed through zines and zine-making. As expressions of insurgencies, resistance, and protest, zines are self-publications that often comprise "writing, photography, collage, illustration and/or other creative work" (Watson & Bennett, 2021, p.

Synaptic strength can vary greatly between synapses. Optical quantal analysis at Drosophila glutamatergic motor neuron synapses shows that short-term plasticity also varies greatly between synapses, even those made by an individual motor neuron. Strong and weak synapses are randomly distributed in the motor neuron nerve terminal, as are facilitating and depressing synapses.

Chicken is an important food animal worldwide and plays an important role in human life by providing meat and eggs. Despite recent significant advances in gut microbiome studies, a comprehensive study of chicken gut bacterial, archaeal, and viral genomes remains unavailable. In this study, we constructed a chicken multi-kingdom microbiome catalog (CMKMC), including 18,201 bacterial, 225 archaeal, and 33,411 viral genomes, and annotated over 6,076,006 protein-coding genes by integrating 135 chicken gut metagenomes and publicly available metagenome-assembled genomes (MAGs) from ten countries.

Rare inherited diseases caused by mutations in the copper transporters (CTR1) or induce copper deficiency in the brain, causing seizures and neurodegeneration in infancy through poorly understood mechanisms. Here, we used multiple model systems to characterize the molecular mechanisms by which neuronal cells respond to copper deficiency. Targeted deletion of CTR1 in neuroblastoma cells produced copper deficiency that produced a metabolic shift favoring glycolysis over oxidative phosphorylation.

Norepinephrine in vertebrates and its invertebrate analog, octopamine, regulate the activity of neural circuits. We find that, when hungry, larvae switch activity in type II octopaminergic motor neurons (MNs) to high-frequency bursts, which coincide with locomotion-driving bursts in type I glutamatergic MNs that converge on the same muscles. Optical quantal analysis across hundreds of synapses simultaneously reveals that octopamine potentiates glutamate release by tonic type Ib MNs, but not phasic type Is MNs, and occurs via the G-coupled octopamine receptor (OAMB).

Conventional drug formulations release active pharmaceutical ingredients (APIs) immediately after administration, while long-acting (LA) drug products are designed for prolonged therapeutic effects, thereby reducing administration frequency and improving patient compliance. The development of LA therapeutics for chronic disease treatment has significantly helped patients adhere to their regimens, reducing the need for daily doses and easing the burden on healthcare systems. Advances in treatment have transformed Human Immunodeficiency Virus (HIV) into a manageable chronic disease, and efforts are underway to eliminate HIV in the future.

The inactivated COVID-19 vaccine has demonstrated high efficacy in the general population through extensive clinical and real-world studies. However, its effectiveness in immunocompromised individuals, particularly those living with HIV (PLWH), remains limited. In this study, 20 PLWH and 15 HIV-seronegative individuals were recruited to evaluate the immunogenicity of an inactivated COVID-19 vaccine in PLWH through a prospective cohort study.

Article Synopsis
  • Rare inherited diseases caused by mutations in copper transporters (CTR1) lead to copper deficiency, which can cause severe neurological issues like seizures and neurodegeneration in infants.
  • The study explores how neuronal cells react to copper deficiency using various genetic model systems, showing that the absence of CTR1 leads to disrupted cellular functions and a shift toward glycolysis.
  • Key findings reveal that the activation of the mTORC1-S6K signaling pathway serves as a protective mechanism to enhance protein synthesis in response to copper deficiency, helping to mitigate some of the detrimental effects on neurons.

Throughout history, the influenza A virus has caused numerous devastating global pandemics. Macrophages, as pivotal innate immune cells, exhibit a wide range of immune functions characterized by distinct polarization states, reflecting their intricate heterogeneity. In this study, we employed the time-resolved single-cell sequencing technique coupled with metabolic RNA labelling to elucidate the dynamic transcriptional changes in distinct polarized states of bone marrow-derived macrophages (BMDMs) upon infection with the influenza A virus.

Article Synopsis
  • This study reviewed 89 female patients with non-metastatic muscle-invasive bladder cancer (MIBC) who underwent neoadjuvant chemotherapy (NAC) followed by radical cystectomy between 2012 and 2023, focusing on the impact of clinical staging changes on surgical eligibility.* -
  • Out of the 75 patients with pre- and post-NAC imaging, 8% were clinically upstaged, meaning their disease progressed such that they were no longer eligible for a vaginal-sparing surgical approach.* -
  • The findings suggest that while upstaging occurred infrequently, interim imaging assessments during NAC could help identify patients who aren’t responding to treatment, potentially preserving their eligibility for less invasive surgical options.*

Identification and morphological analysis of mitochondria-ER contacts (MERCs) by fluorescent microscopy is limited by subpixel resolution interorganelle distances. Here, the membrane contact site (MCS) detection algorithm, MCS-DETECT, reconstructs subpixel resolution MERCs from 3D super-resolution image volumes. MCS-DETECT shows that elongated ribosome-studded riboMERCs, present in HT-1080 but not COS-7 cells, are morphologically distinct from smaller smooth contacts and larger contacts induced by mitochondria-ER linker expression in COS-7 cells.
