While people with multiple sclerosis (MS) are not more likely to contract COVID-19, the incidences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19-related complications may be higher for MS who have comorbidities or taking certain disease modifying therapies (DMT).

CD4(+)CD25(hi) FOXP3(+) regulatory T cells (Tregs) maintain tolerance to self-Ags. Their defective function is involved in the pathogenesis of multiple sclerosis (MS), an inflammatory demyelinating disease of the CNS. However, the mechanisms of such defective function are poorly understood. Recently, we reported that stimulation of TLR2, which is preferentially expressed by human Tregs, reduces...

A more effective vaccine against tuberculosis (TB) is urgently needed. Based on its high genetic homology with Mycobacterium tuberculosis (Mtb), the nonpathogenic mycobacteria, Mycobacterium smegmatis (Ms), could be an attractive source of potential antigens to be included in such a vaccine. We evaluated the capability of lipid-based preparations obtained from Ms to provide a protective respons...

Mycoplasma synoviae infection in chickens and turkeys can cause respiratory disease, infectious synovitis and eggshell apex abnormality; thus it is an economically important pathogen. Control of M. synoviae infection comprises eradication, medication or vaccination. The differentiation of the temperature sensitive (ts+) MS-H vaccine strain from field isolates is crucial during vaccination progr...

The presence of a carbohydrate moiety on asparagine 297 in the Fc part of an IgG molecule is essential for its effector functions and thus influences its vaccine protective effect. Detailed structural carbohydrate analysis of vaccine induced IgGs is therefore of interest as this knowledge can prove valuable in vaccine research and design and when optimizing vaccine schedules. In order to better...

The location of injection and vaccine deposition in ovo is known to be critical to the efficacy of Marek's disease (MD) vaccine protection against MD viral challenge. Vaccine deposition into the amniotic sac or a s.c. or i.m. site of the embryo is required for MD vaccine efficacy. Vaccine deposition into the air cell or allantoic fluid results in chicks that are not adequately protected against...

Unsatisfactory performance of the existing BCG vaccines, especially against the adult pulmonary disease, has urged the need for an effective vaccine against tuberculosis (TB). In this study, we employed differential proteomics to obtain a list of antigens as potential vaccine candidates. Bacterial epitopes being presented at early stages on MHC class I and class II molecules of macrophages infe...
