Synaptic proteome perturbations after maternal immune activation: Identification of embryonic and adult hippocampal changes

Anna Y Yotova et al.

Brain Behav Immun. 2024 Oct;121:351-364. doi: 10.1016/j.bbi.2024.07.040. Epub 2024 Jul 31.

CONCLUSIONS: Our data emphasise the dynamic effects of viral-like MIA on developing and mature hippocampi and provide novel targets for study following prenatal immune challenges. The 22 proteins that changed directionality from the embryonic to adult hippocampus, suggestive of compensatory over-adaptions, are particularly attractive for future investigations.

Inferring Tree-Shaped Single-Cell Trajectories with Totem

António G G Sousa et al.

Methods Mol Biol. 2024;2812:169-191. doi: 10.1007/978-1-0716-3886-6_9.

Single-cell transcriptomics allows unbiased characterization of cell heterogeneity in a sample by profiling gene expression at single-cell level. These profiles capture snapshots of transient or steady states in dynamic processes, such as cell cycle, activation, or differentiation, which can be computationally ordered into a "flip-book" of cell development using trajectory inference methods. However, prediction of more complex topology structures, such as multifurcations or trees, remains...

HSV-1 and Cellular miRNAs in CSF-Derived Exosomes as Diagnostically Relevant Biomarkers for Neuroinflammation

Christian Scheiber et al.

Cells. 2024 Jul 17;13(14):1208. doi: 10.3390/cells13141208.

Virus-associated chronic inflammation may contribute to autoimmunity in a number of diseases. In the brain, autoimmune encephalitis appears related to fluctuating reactivation states of neurotropic viruses. In addition, viral miRNAs and proteins can be transmitted via exosomes, which constitute novel but highly relevant mediators of cellular communication. The current study questioned the role of HSV-1-encoded and host-derived miRNAs in cerebrospinal fluid (CSF)-derived exosomes, enriched from...

The PP2A regulator IER5L supports prostate cancer progression

Jana R Crespo et al.

Cell Death Dis. 2024 Jul 18;15(7):514. doi: 10.1038/s41419-024-06907-z.

Prostate cancer exhibits high prevalence and accounts for a high number of cancer-related deaths. The discovery and characterization of molecular determinants of aggressive prostate cancer represents an active area of research. The Immediate Early Response (IER) family of genes, which regulate Protein Phosphatase 2A (PP2A) activity, has emerged among the factors that influence cancer biology. Here, we show that the less studied member of this family, Immediate Early Response 5 like (IER5L), is...

Protocol to study early lung developmental branching in mouse embryos using explant culture

Salli Talvi et al.

STAR Protoc. 2024 Sep 20;5(3):103198. doi: 10.1016/j.xpro.2024.103198. Epub 2024 Jul 17.

Mouse lung branching morphogenesis creates epithelial tree structures required for respiration. Here, we present a protocol for studying mouse lung developmental branching using lung explant cultures. We describe steps for isolating lungs with a video at embryonic day 12.5 (E12.5) and culturing as an explant for 2 days. We also detail procedures for microscopic imaging on days 0-2 and analysis of peripheral lung buds. This technique has the potential to investigate lung development in various...

TLNRD1 is a CCM complex component and regulates endothelial barrier integrity

Neil J Ball et al.

J Cell Biol. 2024 Sep 2;223(9):e202310030. doi: 10.1083/jcb.202310030. Epub 2024 Jul 16.

We previously identified talin rod domain-containing protein 1 (TLNRD1) as a potent actin-bundling protein in vitro. Here, we report that TLNRD1 is expressed in the vasculature in vivo. Its depletion leads to vascular abnormalities in vivo and modulation of endothelial cell monolayer integrity in vitro. We demonstrate that TLNRD1 is a component of the cerebral cavernous malformations (CCM) complex through its direct interaction with CCM2, which is mediated by a hydrophobic C-terminal helix in...
