Modulation of Natural Killer Cell Cytotoxicity in Human Cytomegalovirus Infection: The Role of Endogenous Class I Major Histocompatibility Complex and a Viral Class I Homolog [PDF]

open access: yes, 1998
Natural killer (NK) cells have been implicated in early immune responses against certain viruses, including cytomegalovirus (CMV). CMV causes downregulation of class I major histocompatibility complex (MHC) expression in infected cells; however, it has ...

Amino Acid‐Sensing Neurons in the Anterior Piriform Cortex Control Brown Adipose Tissue Thermogenesis

open access: yesAdvanced Science, EarlyView.
This study identifies a class of amino acid‐sensing neurons, APCCRH neurons, which regulate BAT thermogenesis. Leucine deficiency alters intrinsic excitability through GCN2 signaling pathway, activating APCCRH neurons, which in turn regulate BAT thermogenesis via projections to the lateral hypothalamus.

O‐GalNAc Glycosylation Activates MBL‐Mediated Complement and Coagulation Cascades to Drive Organotropic Metastasis

open access: yesAdvanced Science, EarlyView.
Upregulated glycosyltransferase GALNT9 in neuroendocrine (NE) carcinomas increases O‐GalNAc glycosylation on cell membrane proteins, particularly Annexin‐A2 (ANXA2). Elevated O‐GalNAc glycan induces the binding of NE cancer cells to mannose binding lectin 2 (MBL2), activating the MBL‐MBL associated serine protease (MBL‐MASP) complement pathway in the ...

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

Multifunctional Biomimetic Nanotherapeutics for Anti‐Oxidative and Anti‐Inflammatory Synergistic Therapy of Corneal Neovascularization

open access: yesAggregate, EarlyView.
An anti‐inflammatory and antioxidant metal‐organic framework (MOF) nanoplatform was prepared via one‐pot self‐assembly. In vitro and in vivo studies demonstrated that the prepared MVPC nanoparticles can effectively scavenge overproduced reactive oxygen species at diseased sites, enhance IL‐10 secretion, and suppress VEGFA expression, offering a novel ...

Cell Membrane‐Coated Lipid Nanoparticles for Drug Delivery

open access: yesAggregate, EarlyView.
This review highlights recent progress in cell membrane‐coated lipid nanoparticles (CMC‐LNPs), focusing on their design, preparation methods, functional integration, and biomedical applications. It discusses various types of LNPs and coating strategies, characterization techniques, therapeutic functions, and applications.

SPLICEIT Fluorescent Sensor for Integrating Dopamine Release with Cellular Resolution

open access: yesAngewandte Chemie, EarlyView.
“Single‐chain protein‐based ligand indication through a chimerically‐engineered integrator tool” (SPLICEIT) is a G‐protein coupled receptor‐based sensor design that leaves a permanent fluorescent mark. We show dopamine detection in primary cultured neurons with a fourfold signal increase normalized to an mCherry (mCh) marker.

Mixed Autoimmune Hemolytic Anemia: A Systematic Review of Epidemiology, Clinical Characteristics, Therapies, and Outcomes

open access: yesAmerican Journal of Hematology, EarlyView.
Mixed autoimmune hemolytic anemia (AIHA) is a rare condition characterized by the presence of both warm and cold autoantibodies, often leading to severe, treatment‐resistant hemolysis. In this systematic review of 81 patients across 35 studies, the median age was 45 years with a notable female predominance.
