How basidiomycete yeast choose carbon sources

Fungi must sense and prioritize nutrients to compete with microbes and form relationships with plants and animals. Brandon Reyes-Chavez, Joshua Kerkaert and Lori Huberman show that the regulator Cbr1 coordinates nutrient use and avoids negative feedback that could block access to some food sources in a basidiomycete fungus.

Cilia, hyperglycemic stress and diabetic retinopathy

Primary cilium dysfunction contributes to diabetic complications, but the mechanisms linking hyperglycemia to cilium loss remain unclear. Jie Ran, Changfeng Wei, Yang Yang, Min Liu and colleagues reveal that PRMT1-HDAC6 crosstalk drives cilium disassembly, identifying a therapeutic target for metabolic ciliopathies.

Theta synchrony and maladaptive motivation in OCD

People with obsessive compulsive disorder recognize that their compulsive behaviors are unnecessary or disproportionate, but still struggle to inhibit habitual responses. Yu Pang, Dongsheng Zhou, Qi Chen and co-workers show that disrupted midfrontal-motor theta phase synchrony weakens effective control that could lead to abnormally strong motivational biases and excessive tendencies to approach reward and avoid punishment.

Fluconazole resistance in Candida parapsilosis

Drug-resistant Candida parapsilosis is an increasing problem in hospitals, but what traits help the fungus survive? Farnaz Daneshnia, Wenjie Fang, Clarissa Nobile, Michael Mansour, Amir Arastehfar and co-authors find that reduced biofilm formation is repeatedly selected for during infection and helps C. parapsilosis evade immune defenses and persist in the host.

Critical roaming and brain dynamics

What accounts for the highly dynamic patterns of brain activity at rest? This computational study by Anagh Pathak and Demian Battaglia shows that slow fluctuations in arousal help reproduce key features of brain regional communication dynamics, with implications for our understanding of critical brain states. Don't miss the accompanying Primer by Audrey Sederberg.

Hunting for antiphage defense systems

Identifying antiphage defense systems is challenging for bacterial species where such systems are understudied. Shelby Andersen, Breck Duerkop and colleagues describe a bioinformatic pipeline that uses a small serine recombinase as a genetic marker to identify novel antiphage defense systems across diverse bacterial phyla.

Visual motion and vestibular coding

Visual motion can bias perceived orientation relative to gravity, so are visual and vestibular signals integrated within cerebellar circuits that encode self-motion? Lex Gómez, Kathleen Cullen and co-workers shows that visual roll motion does not alter Purkinje cell activity or gravity-referenced vestibular coding in the primate cerebellar nodulus and ventral uvula, so such influences likely emerge in downstream circuits.

Editorial

Basic research into Women’s Health should be a priority for all

Despite recent progress in clinical research into Women’s Health, basic research is still lagging behind. This Editorial calls for a renewed focus on basic physiology research into both sexes to close the gap.

Essay

Encrypted peptides

Encrypted peptides are short bioactive fragments hidden within larger proteins that remain largely undercharacterized. This Essay explores how proteolytically released peptides are discovered and how their mechanism of action helps to shape immunity and physiology.
