MRI Characteristics of Japanese Macaque Encephalomyelitis (JME): Comparison to Human Diseases
Tagge et al., Journal of Neuroimaging. 2021.
https://onlinelibrary.wiley.com/doi/10.1111/jon.12868
Magnetic resonance imaging data (MRI) were obtained from 114 Japanese macaques, including 30 animals of both sexes that presented with neurological signs of Japanese macaque encephalomyelitis (JME). Quantitative estimates of blood-brain barrier permeability to gadolinium-based-contrast agent (GBCA) were obtained in acute, GBCA-enhancing lesions, and longitudinal imaging data were acquired for 15 JME animals. Intense, focal neuroinflammation was a key MRI finding in JME. Several features of JME compare directly to human inflammatory demyelinating diseases. The development and validation of noninvasive imaging biomarkers in JME provides the potential to improve diagnostic specificity and contribute to the understanding of human demyelinating diseases.

Trim-Away Mediated Knock Down Uncovers a New Function for Lbh During Gastrulation of Xenopus laevis
Weir et al., Developmental Biology. 2021.
https://pubmed.ncbi.nlm.nih.gov/33159936/
The protein Lbh was identified as necessary for cranial neural crest cell migration in Xenopus. To investigate its role in embryonic events, the authors employed the technique "Trim-Away" to degrade this maternally deposited protein. Trim-Away utilizes the E3 ubiquitin ligase trim21 to degrade proteins targeted with an antibody. Early knockdown of Lbh in Xenopus results in defects in gastrulation that present with a decrease in fibronectin matrix assembly, an increase in mesodermal cell migration and decrease in endodermal cell cohesion. The technique is also effective on a second abundant maternal Protein Kinase C And Casein Kinase Substrate In Neurons 2. Supported by ORIP (R24OD021485) and NIDCR.
