Background: An excess of exosomes, nanovesicles released from all cells and key regulators of brain plasticity, is an emerging therapeutic target for stress-related mental illnesses. The effects of chronic stress on exosome levels are unknown; even less is known about molecular drivers of exosome levels in the stress response.

Methods: We used our state-of-the-art protocol with 2 complementary strategies to isolate neuronal exosomes from plasma, ventral dentate gyrus, basolateral amygdala, and olfactory bulbs of male mice to determine the effects of chronic restraint stress (CRS) on exosome levels.

Background: Catatonia is an underdiagnosed neuropsychiatric condition, with only a few studies focusing on medical sequalae among elderly populations. Delayed treatment results in complications with high morbidity and mortality. Among elderly individuals, one such complication is urinary retention.

Article Synopsis
  • The study aimed to evaluate the safety and effectiveness of implantable collamer lenses (ICLs) for patients with keratoconus through a systematic review and meta-analysis of existing research.
  • A total of 16 observational studies involving 397 eyes were analyzed, showing significant improvements in uncorrected distance visual acuity (UDVA) and various refractive measures, but no substantial changes in corrected distance visual acuity (CDVA).
  • Overall, the findings suggest that ICLs are safe and beneficial for vision correction in keratoconus patients, though limitations such as study design and follow-up duration were noted.

Organ function requires coordinated activities of thousands of genes in distinct, spatially organized cell types. Understanding the basis of emergent tissue function requires approaches to dissect the genetic control of diverse cellular and tissue phenotypes . Here, we develop paired imaging and sequencing methods to construct large-scale, multi-modal genotype-phenotypes maps in tissue with pooled genetic perturbations.

Background: X-linked agammaglobulinaemia (XLA), caused by mutations in BTK, is characterised by low or absent peripheral CD19 + B lymphocytes and agammaglobulinaemia. The mainstay of treatment consists of immunoglobulin replacement therapy (IgRT). As this cannot fully compensate for the immune defects in XLA, patients may therefore continue to be at risk of complications.
