Neuroinflammation is a complex biological process related to a variety of pathologies, often requiring better understanding in order to develop new, targeted therapeutic interventions. Within this context, multimodal Mass Spectrometry Imaging (MSI) has been used to characterise molecular changes in neuroinflammation for biomarker discovery not possible to other techniques. In this study, molecules including bioactive lipids were detected across inflamed regions of the brain in rats treated with lipopolysaccharide (LPS).

The World Health Organization identified the promotion of "Nurturing Care Environments" as a global health priority. Responsive caregiving, 1 of 5 domains describing nurturing care, is critical for healthy child development. Relatively little research has evaluated population-level interventions aimed to increase responsive caregiving during the first 1,000 days of an infant's life.

After a DNA damage signal multiple polymers of ADP ribose attached to poly(ADP) ribose (PAR) polymerases (PARPs) are broken down by the enzyme poly(ADP) ribose glycohydrolase (PARG). Inhibition of PARG leads to a failure of DNA repair and small molecule inhibition of PARG has been a goal for many years. To determine whether biochemical inhibitors of PARG are active in cells we have designed an immunofluorescence assay to detect nuclear PAR after DNA damage.

Self-compassion is associated with depression and anxiety in general samples. Although recent research indicates that dysfunctional maternal attitudes predict the development of perinatal depression and anxiety symptoms, no research to date has examined the construct of self-compassion and its relationship with psychological well-being in perinatal women. Pregnant and postpartum women (N = 189) completed self-report measures of depression and anxiety history, current depression and anxiety symptom severity, and self-compassion.

Cancer cells migrating within a 3D microenvironment are able to adopt either a mesenchymal or amoeboid mode of migration. Amoeboid migration is characterised by membrane blebbing that is dependent on the Rho effectors, ROCK1/2. We identify LIMK2 as the preferred substrate for ROCK1 but find that LIMK2 did not induce membrane blebbing, suggesting that a LIMK2 pathway is not involved in amoeboid-mode migration.

Article Synopsis
  • Hepatocyte growth factor (HGF) enhances prostate cancer cell invasiveness by affecting the actin cytoskeleton through Rho family GTPases, particularly impacting cell migration and invasion.
  • The study identifies that p21 activated kinase 4 (PAK4), activated by HGF, binds to LIM kinase 1 (LIMK1) and phosphorylates it, affecting cofilin levels and altering cell behavior.
  • This research introduces the concept that PAK4 and LIMK1 work together to boost cell migration speed, with HGF signaling being crucial for their interaction and functionality in the process.

Charcot-Marie-Tooth disease (CMT) is the most common inherited disorder of the peripheral nervous system, and mutations in neurofilaments have been linked to some forms of CMT. Neurofilaments are the major intermediate filaments of neurones, but the mechanisms by which the CMT mutations induce disease are not known. Here, we demonstrate that CMT mutant neurofilaments disrupt both neurofilament assembly and axonal transport of neurofilaments in cultured mammalian cells and neurones.
