Granular cell tumors are uncommon neoplasms postulated to derive from Schwann cells. They are histologically unique and exhibit S-100 positivity. Pediatric occurrences are uncommon, and familial cases are rare. A limited number of familial granular cell tumors have been reported. We describe two siblings with granular cell tumors and review the relevant literature.

An unprecedented global outbreak caused by the monkeypox virus (MPXV) prompted the World Health Organization to declare a public health emergency of international concern on July 23, 2022. Therapeutics and vaccines for MPXV are not widely available, necessitating further studies, particularly in drug repurposing area. To this end, the standardization of in vitro infection systems is essential.

Tissues form during development through mechanical compaction of their extracellular matrix (ECM) and shape morphing, processes that result in complex-shaped structures that contribute to tissue function. While observed in vivo, control over these processes in vitro to understand both tissue development and guide tissue formation has remained challenging. Here, we use combinations of mesenchymal stromal cell spheroids and hydrogel microparticles (microgels) with varied hydrolytic stability to fabricate programmable and dynamic granular composites that control compaction and tissue formation over time.

Psoriasis is a chronic inflammatory skin condition characterized by hyperproliferation of keratinocytes and immune dysregulation. Narrow band ultraviolet B (NB-UVB) phototherapy is a common treatment for psoriasis due to its efficacy and safety profile. NOD2 is an intracellular pattern recognition receptor involved in immune responses and inflammation, and its expression is elevated in psoriatic skin.

A major challenge in tuberculosis (TB) therapeutics is that antibiotic exposure leads to changes in the physiology of (), which may enable the pathogen to withstand treatment. While antibiotic-treated has been evaluated in experiments it is unclear if and how long-term treatment with diverse antibiotics with varying treatment-shortening activity (sterilizing activity) affects physiologic processes differently. Here, we used SEARCH-TB, a pathogen-targeted RNA-sequencing platform, to characterize the transcriptome in the BALB/c high-dose aerosol infection mouse model following 4 weeks of treatment with three sterilizing and three non-sterilizing antibiotics.
