Did you know… JCS encourages the involvement of postdocs & other ECRs in the peer review process. Find out more in our reviewer guide: journals.biologists.com/jcs/pages/re... #PRW2026 #PeerReviewWeek We'd like to take this opportunity to thank all the researchers that have reviewed for us.
JCS Cover: Fluorescence micrograph of the female reproductive tract of Drosophila melanogaster. The image highlights the oviduct, spermathecae, seminal receptacle and associated reproductive organs involved in fertilisation and egg deposition, together with mature eggs poised for laying. Cell nuclei are shown in turquoise (DAPI), while enhanced fluorescence displayed in violet provides contrast for visualisation of additional structural features of the reproductive tract. See article by C. A. M. Costa et al. (jcs264328).

In our latest pre-print, we show that mice with the neuropathy-causing GARS1 ∆ETAQ mutation display robust pathology in subsets of peripheral nerves: www.biorxiv.org/content/10.6... Well done @beccasimkin.bsky.social and Aurélie Paulo-Ramos! @uclqsneuromuscular.bsky.social @uclqsion.bsky.social
The images depicts a graphical abstract of the paper. Text abstract: Charcot-Marie-Tooth disease type 2D (CMT2D) results from gain-of-function mutations in GARS1, which encodes glycyl-tRNA synthetase (GlyRS), the enzyme responsible for charging transfer RNA (tRNA) with glycine. There are several CMT2D mouse models, but Gars∆ETAQ/+ is the only one that bears a patient-sourced mutation. Created using CRISPR/Cas9 to model a 12-nucleotide de novo GARS1 deletion identified in an unusually severe CMT2D patient, Gars∆ETAQ/+ mice have previously been shown to display several neuromuscular phenotypes; motor axon loss, denervated neuromuscular junctions (NMJs) and reduced muscle function. Here, we extend these analyses to provide a more comprehensive understanding of both motor and sensory nerve deficits across hind- and fore-limbs. At 3 months, Gars∆ETAQ/+ mice possess sex-independent alterations in the levels of neuropathy biomarkers – including decreased NfL and increased periaxin – alongside reduced muscle endurance and strength, and impairments in the sensory modalities of mechanosensation, proprioception and nociception. Underpinning these dysfunctions, we identified site-specific defects comprising altered sensory neuron populations, muscle spindle loss, reduced motor neuron size, disrupted NMJ innervation and maturation, and reduced axonal transport of signalling endosomes in vivo. Together, these experiments show that Gars∆ETAQ/+ mice display robust and selective peripheral nerve pathology that manifests in a general distal-to-proximal fashion, priming this CMT2D allele for testing treatments and evaluating mechanisms underlying peripheral nerve vulnerability.
