Active zone organization determines the capacity for presynaptic potentiation

This study demonstrates that the baseline spatial organization of voltage-gated calcium channels relative to release sites dictates the capacity for presynaptic plasticity, revealing that only GABA synapses—unlike glutamate synapses—can undergo potentiation through a dramatic reorganization of calcium channel clusters that increases release probability.

Integrated bulk and single-cell RNA-seq analysis reveals psychological stress-related prognostic genes for risk stratification in lung adenocarcinoma

This study integrates bulk and single-cell RNA sequencing to identify a four-gene psychological stress-related signature (CCNB1, TLR4, CCNA2, and EXO1) that effectively stratifies lung adenocarcinoma patients by risk, reveals associations with cell-cycle and immune mechanisms, and predicts chemotherapy sensitivity.

Aberrant B cell differentiation with reduced hypermutation limits humoral response maintenance and breadth in cancer patients

This study reveals that cancer patients exhibit impaired long-term humoral immunity following SARS-CoV-2 vaccination due to B cell–intrinsic defects characterized by reduced somatic hypermutation and aberrant differentiation into atypical T-bet+ populations, a condition that can be mitigated by administering a fourth vaccine dose.

Biofiltration: A breeding ground for antibiotic resistance genes

This study reveals that following a flood-induced shutdown, the biofiltration stage of a municipal wastewater treatment plant became a significant hotspot for the proliferation and persistence of antibiotic-resistant bacteria and genes, with effluent levels of ESBL and carbapenemase-resistant organisms increasing dramatically and showing strong multi-gene co-occurrence.

Host genetic determinants of rotavirus disease and immunity in African children

Through genome-wide association studies of over 3,000 African children, this research elucidates the complex interplay between host genetics, blood group antigens, and rotavirus immunity, identifying a novel LIMS1/HGF signaling pathway that influences anti-rotavirus IgA responses and disease severity to inform the development of more effective vaccines.

Long-range Ret retrograde signaling drives subtype fate and functional identity in a sensory circuit

This study demonstrates that long-range retrograde signaling via the Gdnf receptor Ret stabilizes pioneer neuronal identity and drives functional diversification in the zebrafish posterior lateral line circuit by coupling target-derived cues to specific transcriptional and physiological programs.

Autism-associated Shank3B deletion drives widespread dorsal cortical hyperactivity, amplified sensory responses and accelerated propagation

Using wide-field mesoscale calcium imaging in Shank3B-deficient mice, this study reveals that disruption of the autism-risk gene SHANK3 drives a widespread dorsal cortical hyperactive state that amplifies, destabilizes, and accelerates sensory responses, providing a circuit-level explanation for sensory hyper-responsivity in autism.

Mechanochemical Pattern Formation in a Morphogen-Coupled Tissue Plate: Well-Posedness, Instability Thresholds, and Nonlinear Dynamics

This paper establishes the well-posedness of a mechanochemical plate-diffusion model coupling tissue deformation and morphogen concentration, and through spectral analysis, demonstrates that the sign of deformation-to-morphogen feedback critically determines the stability of the homogeneous state, thereby identifying the linear instability mechanisms that precede nonlinear pattern formation.
