Sex Differences in Cannabinoid Withdrawal in Rats
2026-09-30
Brewer and colleagues show that withdrawal from the synthetic cannabinoid agonist WIN 55,212-2 differs qualitatively between male and female rats, even when overall withdrawal scores are comparable. Their sex-aware design separates precipitated somatic withdrawal, spontaneous withdrawal, locomotor activity, and later anxiety-like behavior, providing practical guidance for cannabinoid dependence studies.

Guanabenz Acetate in Immune-Pathway Assays
2026-09-28
Guanabenz Acetate is an α2-adrenergic receptor agonist that can help researchers test how adrenergic GPCR inputs affect cellular responses. This article connects its subtype pharmacology to a SARS-CoV-2 GADD34 study while carefully distinguishing established findings from testable hypotheses.

Tetrandrine: Research Uses, Mechanism & Handling
2026-09-27
Tetrandrine is a natural-product alkaloid used as a research probe for calcium-channel modulation and related signaling questions. Its product specifications support practical guidance on formulation and storage, while the cited SARS-CoV-2 NSP15 screening study does not establish tetrandrine as an antiviral hit.

Necrostatin-1 (Nec-1): Assay Guide
2026-09-26
This practical guide explains how to use Necrostatin-1 (Nec-1), SKU A4213, to investigate RIP1-dependent necroptosis while managing solvent, dose, and interpretation challenges. It distinguishes product-reported activity values from workflow starting points and shows why viability results should be supported by pathway-specific evidence.

TRPV1+ Sensory Nerves Suppress Inflammation
2026-09-26
Song and colleagues report that stimulating TRPV1+ sensory afferents at the nape engages brainstem and autonomic pathways that suppress systemic inflammatory responses. The study links peripheral sensory input to catecholamine release and splenic gene-expression changes, while highlighting important limits on generalizing this neural mechanism to other inflammatory models.

RNAi Reveals SARS-CoV-2 Release Factors
2026-09-25
Kerr et al. used an arrayed RNA interference screen and virus-production measurements at two timepoints to identify host pathways that support SARS-CoV-2 replication, including vesicle-mediated transport linked to viral release. Validation across the original virus and Delta and Omicron variants, together with inhibition of Rab11a-mediated cargo delivery by CDKI-73, points to host-directed antiviral hypotheses while leaving important questions about specificity and therapeutic transferability.

Parthenolide and ROS-Linked Apoptosis in Lymphoid Cancer
2026-09-24
Across seven lymphoid malignancy cell lines, parthenolide reduced resazurin-measured metabolic activity and was associated with apoptosis, increased reactive oxygen species, glutathione depletion, and loss of mitochondrial membrane potential. The study’s value lies in combining this cross-disease cell panel with redox and cell-death measurements, while its in vitro findings call for careful interpretation of metabolic readouts and further mechanistic validation.

Nanoparticle Uptake by Human Corneal Epithelial Cells
2026-09-24
Azadi and David examined how PLGA nanoparticle size and surface modification affect uptake by human corneal epithelial cells in a model that includes simulated mucosal conditions. Their results identify energy-dependent endocytosis—especially macropinocytosis and caveolae-mediated uptake—as dominant routes, while showing that uptake depends on both particle size and surface chemistry.
