Permanent defects in renal medullary structure and function after reversal of urinary obstruction.
JCI Insight
January 2025
Division of Nephrology, Department of Medicine, Vanderbildt University Medical Center, Nashville, United States of America.
Urinary obstruction causes injury to the renal medulla, impairing the ability to concentrate urine, and increasing the risk of progressive kidney disease. However, the regenerative capacity of the renal medulla after reversal of obstruction is poorly understood. To investigate this, we developed a mouse model of reversible urinary obstruction.

JAMA Ophthalmol
January 2025
Truhlsen Eye Center, Department of Ophthalmology and Visual Sciences, University of Nebraska Medical Center, Omaha.
Importance: Randomized clinical trials have shown the safety and efficacy of faricimab as a novel vascular endothelial growth factor and angiopoietin-2 inhibitor in the treatment of neovascular age-related macular degeneration (nAMD) and macular edema of various etiologies. However, more rare adverse events may not be considered in clinical trials.
Objective: To describe 3 eyes that developed irreversible vision loss following initial mild intraocular inflammation (IOI) to faricimab.
The LIM-domain-only protein LMO2 and its binding partner LDB1 are differentially required for class switch recombination.

The LIM-domain-only protein LMO2 interacts with LDB1 in context-dependent multiprotein complexes and plays key roles in erythropoiesis and T cell leukemogenesis, but whether they have any roles in B cells is unclear. Through a CRISPR/Cas9-based loss-of-function screening, we identified LMO2 and LDB1 as factors for class switch recombination (CSR) in murine B cells. LMO2 contributes to CSR at least in part by promoting end joining of DNA double-strand breaks (DSBs) and inhibiting end resection.

The differentiation and functionality of virus-specific T cells during acute viral infections are crucial for establishing long-term protective immunity. While numerous molecular regulators impacting T cell responses have been uncovered, the role of cellular prion proteins (PrPc) remains underexplored. Here, we investigated the impact of PrPc deficiency on the differentiation and function of virus-specific T cells using the lymphocytic choriomeningitis virus (LCMV) Armstrong acute infection model.
