    Comparison of freshly cultured versus cryopreserved mesenchymal stem cells in animal models of inflammation: A pre-clinical systematic review

    Chintan Dave, Shirley HJ Mei ... Lauralyn McIntyre
    Administration of cryopreserved as compared freshly cultured MSCs do not appear to negatively impact measures of in vivo efficacy or in vitro potency in animal models of inflammation.

    Transmission networks of SARS-CoV-2 in Coastal Kenya during the first two waves: A retrospective genomic study

    Charles N Agoti, Lynette Isabella Ochola-Oyier ... George Githinji
    Genomic analysis of initial SARS-CoV-2 waves in Kenya revealed Mombasa City as a key gateway for variants entering Coastal Kenya with onward inter-county transmission highlighting significance of surveillance in major cities for early warning of lineages entering local populations.

    Adaptor linked K63 di-ubiquitin activates Nedd4/Rsp5 E3 ligase

    Lu Zhu, Qing Zhang ... Scott D Emr
    Arrestin-related trafficking adaptors (ARTs) undergo a K63 linked di-ubiquitin modification to promote Rsp5 E3 ligase recruitment and enhance cargo protein ubiquitination.

    Active site geometry stabilization of a presenilin homolog by the lipid bilayer promotes intramembrane proteolysis

    Lukas P Feilen, Shu-Yu Chen ... Harald Steiner
    Biochemical studies in combination with computational modeling and molecular dynamics simulations reveal that the lipid bilayer promotes intramembrane proteolysis by stabilizing the enzyme-substrate complex and the protease active site.

    Tyrosine phosphorylation tunes chemical and thermal sensitivity of TRPV2 ion channel

    Xiaoyi Mo, Peiyuan Pang ... Jing Yao
    Mg2+-dependent JAK1-mediated phosphorylation sensitizes TRPV2 activity and thermo-threshold, which is counterbalanced by PTPN1-mediated dephosphorylation, highlighting a role of phosphorylation homeostasis in setting the basal activity of TRPV2.

    Cells use molecular working memory to navigate in changing chemoattractant fields

    Akhilesh Nandan, Abhishek Das ... Aneta Koseska
    Combined experimental and theoretical analysis identifies a molecular mechanism akin to working memory that enables single cells to perform complex navigation tasks in changing growth factor fields, beyond simple stimulus-response associations.

    Modelling the response to vaccine in non-human primates to define SARS-CoV-2 mechanistic correlates of protection

    Marie Alexandre, Romain Marlin ... Rodolphe Thiébaut
    A model-based approach for modelling the immune control of viral dynamics is applied to quantify the effect of several SARS-CoV-2 vaccine platforms and to define mechanistic correlates of protection.

    Neural tracking of phrases in spoken language comprehension is automatic and task-dependent

    Sanne ten Oever, Sara Carta ... Andrea E Martin
    The brain’s projection of linguistic knowledge onto speech is reflected by the automatic, reflexive neural tracking of phrases, while the distribution of phrasal-rate tracking and connectivity, particularly the involvement of inferior frontal cortex, is subject to task demands.

    Biophysical Kv3 channel alterations dampen excitability of cortical PV interneurons and contribute to network hyperexcitability in early Alzheimer’s

    Viktor J Olah, Annie M Goettemoeller ... Matthew JM Rowan
    Electrophysiological and genetic analyses reveal a biophysical mechanism in parvalbumin interneurons, uncoupled from changes in gene expression, resulting in reduced cortical inhibition in early-stage Alzheimer's disease.
