Most adhesion GPCRs undergo autoproteolytic cleavage during receptor biosynthesis, resulting in non-covalently bound N- and C-terminal fragments (NTF and CTF) that remain associated during receptor trafficking to the plasma membrane. While substantial evidence supports increased G protein signaling when just the CTF is expressed, there is an ongoing debate about whether NTF removal is required to initiate signaling in the context of the wild-type receptor. Here, we use adhesion GPCR latrophilin-3 (ADGRL3) as a model receptor to investigate tethered agonist-mediated activation.

The membrane-proximal external region (MPER) of the HIV-1 envelope is a target for broadly neutralizing antibodies (bnAbs), and vaccine-elicited MPER-directed antibodies have recently been reported from a human clinical trial. In this study, we sought to identify MPER-directed nAbs in simian immunodeficiency virus (SIV)-infected rhesus macaques. We isolated four lineages of SIV MPER-directed nAbs from two SIV-infected macaques.

Patients benefit from and appreciate the option to use telehealth with their providers. Such patient expectations have therefore led to new questions about the factors that affect providers' willingness to adopt telehealth as part of their clinical practice. We interviewed 19 physicians across four specialties with differential rates of telehealth use (Psychiatry, Anesthesiology, Physical Medicine & Rehabilitation [PM&R], and Ophthalmology) to discern the barriers and incentives to telehealth adoption among physicians.

Breast cancer presents a significant global health challenge, necessitating continued innovation in diagnostic and therapeutic approaches. Recent advances have led to the identification of cancer-associated fibroblasts, which are highly prevalent in breast cancers and express fibroblast activation proteins (FAPs), as critical targets. FAP-specific radiotracers, when used with PET/CT and SPECT/CT, have significant potential for improving early breast cancer detection, staging, treatment response monitoring, and therapeutic intervention.

The adoption of large language models (LLMs) in healthcare demands a careful analysis of their potential to spread false medical knowledge. Because LLMs ingest massive volumes of data from the open Internet during training, they are potentially exposed to unverified medical knowledge that may include deliberately planted misinformation. Here, we perform a threat assessment that simulates a data-poisoning attack against The Pile, a popular dataset used for LLM development.

The Cognitive and Linguistic Scale (CALS) was developed to serially monitor cognitive recovery of children and young people after severe acquired brain injury (ABI), during inpatient rehabilitation. The CALS can be used to derive Cognitive Ability Estimates (CAE) which are Rasch-propertied (unidimensional, interval-scale) and therefore may be ideally applied for use in research including within the context of clinical trials. Here, we used established statistical distribution-based and expert consensus-based methods to estimate the Minimal Clinically Important Difference (MCID) for CAE derived from the CALS.

Introduction: Asian American, Native Hawaiian, and Pacific Islander (AANHPI) people represent one of the largest and most rapidly growing groups in the United States and are often aggregated as a homogeneous, rather than diverse, population in medical research and education. Currently, few educational interventions focus on the disaggregation of AANHPI patient populations and the improvement of knowledge about health disparities that affect AANHPI patients.
Methods: We developed, implemented, and facilitated a workshop for medical students to address AANHPI health disparities, adaptable for in-person and online formats.

Introduction: Rhesus macaques have long been a focus of research for understanding immune responses to human pathogens due to their close phylogenetic relationship with humans. As rhesus macaque antibody germlines show high degrees of polymorphism, the spectrum of database-covered genes expressed in individual macaques remains to be determined.
Methods: Here, four rhesus macaques infected with SHIV became a study of interest because they developed broadly neutralizing antibodies against HIV-1.

A significant number of individuals with asthma have poorly controlled daily symptoms and utilize dietary supplements such as ginger in a quest for improved symptom control; however, its effectiveness at improving the control of symptoms is unproven. We questioned whether low-dose oral ginger would improve subjective and objective measurements of asthma control in mild-to-moderate asthmatics. We performed a randomized, placebo-controlled, double-blinded study of a low dose (1 g twice daily) of a dietary supplement of ginger in 32 mild-to-moderate uncontrolled asthmatics over a 2-month trial period while maintaining daily conventional asthma therapies.

Background: Converging evidence from clinical neuroimaging and animal models has strongly implicated dysfunction of thalamocortical circuits in the pathophysiology of schizophrenia. Preclinical models of genetic risk for schizophrenia have shown reduced synaptic transmission from auditory thalamus to primary auditory cortex, which may represent a correlate of auditory disturbances such as hallucinations. Human neuroimaging studies, however, have found a generalized increase in resting state functional connectivity (RSFC) between whole thalamus and sensorimotor cortex in people with schizophrenia (PSZ).

With current treatments addressing only a fraction of pathogens and new viral threats constantly evolving, there is a critical need to expand our existing therapeutic arsenal. To speed the rate of discovery and better prepare against future threats, we establish a high-throughput platform capable of screening compounds against 40 diverse viral proteases simultaneously. This multiplex approach is enabled by using cellular biosensors of viral protease activity combined with DNA-barcoding technology, as well as several design innovations that increase assay sensitivity and correct for plate-to-plate variation.
