mRNA vaccines have been shown to be effective in combating the COVID-19 pandemic. The amount of research on use mRNAs as preventive and therapeutic modalities has undergone explosive growth last few years. Nonetheless, issue stability molecules their translation efficiency remains incompletely resolved. These characteristics directly affect expression level a desired protein. Regulatory elements RNA—5′ 3′ untranslated regions (UTRs)—are responsible for efficiency. An optimal combination...

Background Infection with Mycobacterium tuberculosis (Mtb) results in different clinical outcomes ranging from asymptomatic containment to rapidly progressing (TB). The mechanisms controlling TB progression immunologically-competent hosts remain unclear. Methodology/Principal Findings To address these mechanisms, we analyzed a panel of genetically heterogeneous (A/SnxI/St) F2 mice, originating TB-highly-susceptible I/St and more resistant A/Sn mice. In mice the rates differed. that did not...

IL-11 is multifunctional cytokine whose physiological role in the lungs during pulmonary tuberculosis (TB) poorly understood. Here, using vivo administration of specific antibodies against IL-11, we demonstrate for first time that blocking diminishes histopathology and neutrophilic infiltration lung tissue TB-infected genetically susceptible mice. Antibody treatment decreased levels other key inflammatory cytokines not belonging to Th1 axis, down-regulated mRNA expression. This suggests...

Earlier we demonstrated that blocking of interleukin 11 (IL-11) by systemic administration anti–IL-11 antibodies attenuates severity Mycobacterium tuberculosis infection in mice. The substitution W147A the IL-11 molecule creates form cytokine capable to disrupt gp130/IL11R signaling complex formation, thus serving as a high-affinity specific antagonist IL-11–mediated signaling. We hypothesized this mutant may serve an effective tool for inhibition native activity vivo. established...

Tuberculosis, a disease caused by the bacterium Mycobacterium tuberculosis, is major public health concern. Innate and adaptive immunity provide robust defense against pathogens. However, M. which co-evolved with humans, has acquired many mechanisms to evade immune response ensure its intracellular existence long-term survival within host. Moreover, emerging evidence suggests that this secretive can alter expression of regulatory noncoding RNAs (including microRNAs), leading dysregulation...

Introduction. Sarcoidosis-associated pulmonary fibrosis still lacks biomarkers to predict progression. Whole-genome association studies and other genetic research over the past few years have identified several single nucleotide polymorphisms that are associated with an increased risk of developing fi brosis. In sarcoidosis, relatively reliable predictors disease activity include serum angiotensin-converting enzyme, soluble interleukin-2 receptor (sIL-2R) chitotriosidase. Levels inetrleukin-5...
