Histological Severity Risk Factors Identification in Juvenile-Onset Recurrent Respiratory Papillomatosis: How Immunohistochemistry and AI Algorithms Can Help?

Juvenile-onset recurrent respiratory papillomatosis (JoRRP) is a condition characterized by the repeated growth of benign exophytic papilloma in the respiratory tract. The course of the disease remains unpredictable: some children experience minor symptoms, while others require multiple interventions due to florid growth. Our study aimed to identify histologic severity risk factors in patients with JoRRP.

Deep Learning-Based Classification of Inherited Retinal Diseases Using Fundus Autofluorescence.

. In recent years, deep learning has been increasingly applied to a vast array of ophthalmological diseases. Inherited retinal diseases (IRD) are rare genetic conditions with a distinctive phenotype on fundus autofluorescence imaging (FAF).

Requirement of Mucosa-Associated Lymphoid Tissue Lymphoma Translocation Protein 1 Protease Activity for Fcγ Receptor-Induced Arthritis, but Not Fcγ Receptor-Mediated Platelet Elimination, in Mice.

Objective: Fcγ receptors (FcγR) play important roles in both protective and pathogenic immune responses. The assembly of the CBM signalosome encompassing caspase recruitment domain-containing protein 9, B cell CLL/lymphoma 10, and mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT-1) is required for optimal FcγR-induced canonical NF-κB activation and proinflammatory cytokine release. This study was undertaken to clarify the relevance of MALT-1 protease activity in FcγR-driven events and evaluate the therapeutic potential of selective MALT-1 protease inhibitors in FcγR-mediated diseases.

DPP9 enzymatic activity in hematopoietic cells is dispensable for mouse hematopoiesis.

Dipeptidyl peptidase 9 (DPP9) is a ubiquitously expressed intracellular prolyl peptidase implicated in immunoregulation. However, its physiological relevance in the immune system remains largely unknown. We investigated the role of DPP9 enzyme in immune system by characterizing DPP9 knock-in mice expressing a catalytically inactive S729A mutant of DPP9 enzyme (DPP9 mice).

Vitamin D receptor agonists as anti-inflammatory agents.

1alpha,25-dihydroxyvitamin D3 (1,25-[OH]2D3), the biologically active form of vitamin D, is a secosteroid hormone that is essential for bone and mineral homeostasis. In addition, this hormone regulates the growth and differentiation of many cell types and has pronounced immunoregulatory and anti-inflammatory properties. Current therapeutic indications include osteoporosis, secondary hyperparathyroidism and psoriasis, but the anti-proliferative, prodifferentiative, antibacterial, immunomodulatory and anti-inflammatory properties of vitamin D receptor agonists could be exploited in a variety of additional clinical conditions.
