We performed a retrospective study of patients with CoN and analyzed the clinical and laboratory findings of patients with CoN and IN diagnosed between 1999 and 2018 in a clinical immunology unit of a large pediatric hospital. We identified 88 patients, 51 with IN and 37 with CoN. Fifty-seven percent were males, and 43% were females, ranging from 1 month to 19 years. The median age at onset was 8 months, and the median at diagnosis was 36 months. Consanguinity was observed in 57% of the cases, and a history of recurrent infections in the siblings was found in 27.3%. The most common infectious complications were ear, nose, and throat (ENT) infections, skin and soft tissue infections, and lung infections. Patients with CoN were classified into seven syndromes: 9 with severe congenital neutropenia, 11 with cyclic neutropenia, 6 with glycogen storage disease type 1b, 5 with poikiloderma with neutropenia, 3 with Griscelli syndrome, 2 with Hermansky-Pudlak syndrome type II, and 1 with Cohen syndrome. This study provides a comprehensive overview of CoN and IN in a pediatric cohort from Morocco, representing the country's most considerable single-center investigation of these conditions.

Based on our recent finding to study the potential effect of mTOR on ATG13 inactivation in chronic muscle fatigue, we report that biweekly oral administration with MHY1485, a potent inducer of mTOR, develops chronic illness in mice resulting in severe muscle weakness. As a mechanism, we observed that MHY1485 feeding impaired ATG13-dependent autophagy, caused the infiltration of inflammatory M1 macrophages (Mφ), upregulated IL6 and RANTES by STAT3 activation, and augmented demyelination in muscle-serving nerve fibers. Interestingly, these mice displayed worsened muscle fatigue during 2-day post-treadmill exercise, suggesting the critical role of chronic mTOR activation in potential PEM pathogenesis. Interestingly, ATG13-repressor mice exhibited enhanced infiltration of M1Mφ cells, STAT3 activation, demyelination of nerve fibers, and PEM-like symptoms, suggesting the potential role of ATG13 impairment in post-exertional fatigue. HIGHLIGHTS: The potential role of mTOR activation in post-exertional fatigue is highlighted. As a molecular mechanism, mTOR activation augments autophagy impairment via ATG13 inactivation.

Data were obtained from the Global Burden of Disease (GBD) 2021 study. Trends in ASIR, ASPR, and ASMR were analyzed using Joinpoint regression to calculate annual percentage change (APC) and average APC (AAPC). Bayesian age-period-cohort (BAPC) modeling was applied to project future ASIR trends.

Asthma exhibited significant declines in ASIR (-1.23% AAPC), ASPR (-1.49%), and ASMR (-4.4%). Conversely, T1DM showed rising ASIR (+ 1.16%) and ASPR (+ 1.15%) alongside declining ASMR (-2.62%). Psoriasis (+ 0.74%) and IBD (+ 2.09%) also showed rising ASIR. Gender differences were notable, with greater T1DM ASIR increases in males and more significant asthma improvements in females. By 2046, the ASIR of T1DM, psoriasis, and RA is projected to reach 5.8, 80.9, and 15.54 per 100,000, respectively, while asthma is expected to decline to 330.98 per 100,000.

In order to maintain tolerance or initiate immune responses, DCs must be activated in a balanced and regulated manner via diverse signaling pathways. By using a variety of pharmacological components, we can interfere with their different signaling pathways such as the mammalian target of rapamycin (mTOR) to appropriately modulate DC activity. In the current study, we administered RAD001 to DCs to examine the impact of mTOR inhibition on both the maturation stage and the expression of inflammatory and anti-inflammatory molecules in DCs. Pure monocytes were cultivated and stimulated with GM-CSF and IL-4 to generate immature DCs, which were then treated with RAD001. The phenotype of the DCs was determined by labeling surface markers and analyzing them using flow cytometry. Afterward, real-time PCR was carried out to evaluate the expression of inflammatory and anti-inflammatory genes. The administration of RAD001 to DCs led to a significant upregulation in the gene expression of inflammatory molecules such as IL-12, IL-1β, tumor necrosis factor (TNF)-α, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-KB). Conversely, RAD001 treatment resulted in a decrease in the gene expression of anti-inflammatory factors IL-10 and indoleamine 2,3-dioxygenase (IDO). However, the expression of differentiation and antigen presentation-related markers CD11c and human leukocyte antigens (HLA)-DR in RAD001-treated DCs was lower and higher compared to the control group that did not receive the treatment, respectively. Taken together, our findings indicated that RAD001 treatment of DCs can be a promising therapeutic approach for the generation of immunogenic DCs in order to barricade tumor growth.
