IgA vasculitis (IgAV) generally occurs in young people and presents with a tetrad of symptoms: purpura, abdominal pain, arthralgia, and nephritis. However, it may have an atypical course without the typical tetrad. Diffuse alveolar hemorrhage (DAH), heart failure, and stroke are known complications of IgAV but are all very rare.

- * He was initially treated with corticosteroids but developed refractory pneumothorax, which made managing the air leakage challenging.
- * The treatment was successfully modified to include mepolizumab, an anti-interleukin-5 therapy, and an endobronchial Watanabe spigot, resulting in the resolution of the pneumothorax and no recurrence of EP post-treatment.
Background: Transgenic (Tg) mice are widely used in biomedical research, and they are typically generated by injecting transgenic DNA cassettes into pronuclei of one-cell stage zygotes. Such animals often show unreliable expression of the transgenic DNA, one of the major reasons for which is random insertion of the transgenes. We previously developed a method called "pronuclear injection-based targeted transgenesis" (PITT), in which DNA constructs are directed to insert at pre-designated genomic loci.

We found that Foxc1 and Foxc2 (Foxc1/2) are expressed in NPs and SPs. Systemic deletion of Foxc1/2 2 days after the onset of metanephros development (embryonic day 13.

Although many transcription factors (TFs) are necessary for cell-state maintenance in glomeruli, their roles in transcriptional regulation are not well understood.
Methods: The distribution of H3K27ac histones in human glomerulus cells was analyzed to identify superenhancer-associated TFs, and ChIP-seq and transcriptomics were performed to elucidate the regulatory roles of the TFs.
