Newest firstThe increasing prevalence of cannabis use, including among pregnant women, highlights the critical need for a deeper understanding of prenatal cannabis exposure. This study aimed to develop a standardized cross-species inhalation exposure protocol to administer the principal psychoactive component of cannabis, Δ9-tetrahydrocannabinol (THC), to prairie voles (Microtus ochrogaster) and laboratory rats (Rattus norveg…
Open article record in new tab ↗The endocannabinoid system modulates diverse physiological processes via two endogenous lipid ligands, 2-arachidonoylglycerol (2-AG) and anandamide (AEA); however, their specific spatiotemporal dynamics remain poorly understood owing to the lack of selective probes. Here, we developed GRAB 2-AG2.0 and GRAB AEA2.0 , two genetically encoded fluorescent sensors that selectively detect 2-AG and AEA, respectively. Both…
Open article record in new tab ↗Background Cannabis derivatives have been reported to possess antinociceptive properties. However, oral delivery is limited by poor bioavailability, stability, and reliability of effects. Previously, we reported an analgesic effect of the aqueous complex Δ9-tetrahydrocannabinol/2-hydroxypropyl-β-cyclodextrin (THC/HPβCD) after intracerebroventricular administration in male rats. Methods Here, we investigated the an…
Altered states of consciousness (ASC) refer to states that differ markedly from normal waking consciousness. ASC may occur spontaneously, such as in dreaming, or through consciousness modifying techniques, from meditation, to cannabis and psychedelics. The etymology behind the term psychedelic, meaning mind-manifesting, is based on the hypothesis that certain substances, including serotonergic hallucinogens, do no…
Open article record in new tab ↗Background: The complexity of diagnosing and treating biofilm-associated infections necessitates a comprehensive strategy to mitigate the rising rates of antimicrobial resistance (AMR). Microtiter plate methods are used globally for determination of biofilm eradication concentrations (MBEC) but few have been adapted to observe pharmacodynamic observations. Here, we describe a method which allows for both static an…
Open article record in new tab ↗Filamentous fungi, such as Aspergillus species, use microtubule transport to move early endosomes. Other cargos, such as peroxisomes and mRNAs, "hitchhike" on early endosomes to move throughout the long hyphae of these organisms. In Aspergillus nidulans, peroxisomes hitchhike on early endosomes using the endosomal protein PxdA and the peroxisomal protein AcbdA. The HookA adaptor protein links endosomes to microtub…
Open article record in new tab ↗Pseudomonas aeruginosa is a major opportunistic pathogen, responsible for healthcare-associated urinary tract infections. Its metabolic flexibility and genomic plasticity promote its survival and adaptation in complex environments. Here, we conducted an in-depth analysis of three pairs of sequential P. aeruginosa urinary isolates, named "early" and "late", from three patients to investigate metabolic and phenotypi…
Medical records and omics data are rapidly becoming standard in healthcare settings, which characterize the whole-person from dysfunctional molecules to phenotypes, and thus offer potential for precise disease diagnosis and target discovery. Whereas, it remains an open problem to systematically integrate and interprete medical record and omics data of individual patients. In this study, for the first time, we prop…
Open article record in new tab ↗ABSTRACT The need for improved treatments for chronic pain has driven increased interest in cannabis-based therapeutics. Peripheral dorsal root ganglion (DRG) neurons, including nociceptors, express cannabinoid receptors (CB1 and CB2), suggesting that modulation of DRG excitability may provide an effective strategy for peripheral analgesia. Here, we investigated the effects of cannabidiol (CBD), Δ 9 -tetrahydrocan…
Open article record in new tab ↗Terpenoids are ubiquitous, structurally diverse natural products found across the three domains of life. One of the most commonly observed and well-studied terpenoids is the volatile, petrichoric compound geosmin, responsible for the earthy smell of soil to which humans are receptive down to a few parts per trillion. Bioinformatic analysis of bacterial geosmin synthase (GeoA)-encoding gene clusters reveals that ma…
Open article record in new tab ↗Prenatal cannabis use is on the rise, and observational studies suggest that such use results in neurodevelopmental deficits in the offspring. Because observational studies can be confounded by unaccounted factors, we studied the neurodevelopmental consequences, at the molecular level, of prenatal cannabis use. We applied an integrated multi-omics approach, combining transcriptomics and global proteomics, to first…
Open article record in new tab ↗The Klebsiella oxytoca Species Complex (SC) represents an emerging healthcare-associated group of opportunistic pathogens. The capsular polysaccharide is a virulence determinant and target for novel vaccines, monoclonal antibodies and phage therapy. In the absence of broadly accessible phenotyping techniques, prediction of capsule types from whole-genome sequence data is critical for understanding capsule diversit…
Open article record in new tab ↗Streptococcus pyogenes is a globally important pathogen responsible for at least 500,000 deaths a year, causing significant burden on healthcare systems. It is the causative agent for ailments such as impetigo and strep throat to septicaemia and necrotizing fasciitis. Assessment of genetic relatedness for the detection of outbreaks within communities or healthcare facilities is vital in decreasing the propagation…
Open article record in new tab ↗Cannabinoid receptor 2 (CB 2 R) is highly expressed on immune cells, but its role in T cell metabolism remains unclear. Here, we show that CB 2 R activation rapidly increases glucose uptake in human Jurkat T cells and drives a broader metabolic reprogramming away from glycolysis toward oxidative metabolism and the pentose phosphate pathway. Pharmacological CB 2 R activation increased mitochondrial mass, spare resp…
Open article record in new tab ↗Many commensal bacteria that peacefully reside in the human microbiome are also able to cause acute opportunistic infections. Emerging evidence suggests that within-host evolution contributes to infection, but the genetic mechanisms facilitating the progression of opportunistic pathogens from carriage to acute infection remain unknown. Here, we prospectively collected native samples from four microbiome niches of…
Open article record in new tab ↗Capsid stability is vital for virion survival as the capsid must withstand varying environmental challenges such as pH and temperature to allow the virus to reach a target cell. Noroviruses are non-enveloped, icosahedral, positive-sense RNA viruses of importance to human health globally, with no approved vaccine or antiviral available. Despite this, the molecular mechanisms behind norovirus capsid stability and ca…
Open article record in new tab ↗Dysregulated gut homing of leukocytes drives chronic inflammation in Crohn’s disease (CD). We employed phage display selection campaigns with libraries of stabilized, constrained peptides against endogenous conformation states of the cannabinoid receptor CB 2 R on human T cells, to discover novel receptor antagonists with potential to inhibit gut homing. Cluster and frequency analysis of 50,000 enriched sequences…
Open article record in new tab ↗Background and Hypothesis Motor alterations represent an important component of psychotic disorders. Chronic cannabis use, a key risk factor for psychosis, is also associated with sensorimotor dysfunctions. Yet, the hypothesis of a common sensorimotor disturbance remains underinvestigated. Study Design. In this study, we examined submovements, elementary units of motor output, to search for common subclinical impa…
Open article record in new tab ↗The effect that environmental conditions have on community and network assembly processes remains unclear, in part because these processes operate at multiple scales. Because marine primary producers and microinvertebrates have limited mobility, are susceptible to multiple stressors, and can be observed interacting in situ, their habitat-based interactions provide an informative system for disentangling network or…
Open article record in new tab ↗Obesity and related conditions such as dyslipidemia impose an increasing burden on healthcare systems worldwide. These conditions are associated with altered postprandial chylomicron (CM) metabolism, the elusive and critical first step in lipid metabolism. This step remains elusive because it is governed by large interindividual variations and a complex set of intestinal processes. In particular, the second meal e…
