Article Synopsis
  • The need for more effective tuberculosis (TB) vaccines is crucial, as TB remains the deadliest infectious disease worldwide, but current methods to evaluate potential vaccines are slow and expensive due to unclear immune protection correlates.
  • Human-derived correlate of risk (COR) gene signatures could serve as valuable endpoints in preclinical evaluations of TB treatments, allowing for more defined and practical assessments.
  • The study identifies specific COR signatures, like RISK6, Sweeney3, and BATF2, which show promise in correlating with disease progression in preclinical models, especially when these models are closely matched to human TB infection conditions.

The three programs that make up the Immune Mechanisms of Protection Against Centers (IMPAc-TB) had to prioritize and select strains to be leveraged for this work. The CASCADE team based at Seattle Children's Research Institute are leveraging M.tb H37Rv, M.

At the beginning of the COVID-19 pandemic those with underlying chronic lung conditions, including tuberculosis (TB), were hypothesized to be at higher risk of severe COVID-19 disease. However, there is inconclusive clinical and preclinical data to confirm the specific risk SARS-CoV-2 poses for the millions of individuals infected with (M.tb).

Unlabelled: It is not clear whether human progression to active tuberculosis disease (TB) risk signatures are viable endpoint criteria for evaluations of treatments in clinical or preclinical development. TB is the deadliest infectious disease globally and more efficacious vaccines are needed to reduce this mortality. However, the immune correlates of protection for either preventing infection with or preventing TB disease have yet to be completely defined, making the advancement of candidate vaccines through the pipeline slow, costly, and fraught with risk.

Article Synopsis
  • Nontuberculous mycobacteria (NTM) are germs that can cause serious infections in both kids and adults, especially in people with weak immune systems.
  • In this study, scientists looked at a special protein called CBLB that helps the immune system fight off NTM infections in mice.
  • They discovered that CBLB is important for stopping the spread of these germs by helping the body form a defense structure called granuloma, which helps fight off the infection.

() is an opportunistic pathogen usually colonizing abnormal lung airways and is often seen in patients with cystic fibrosis. Currently, there is no vaccine available for in clinical development. The treatment of -related pulmonary diseases is peculiar due to intrinsic resistance to several commonly used antibiotics.

Mycobacterium bovis is responsible for bovine tuberculosis in both animals and humans. Despite being one of the most important global zoonotic disease, data related to the ecology and pathogenicity of bovine tuberculosis is scarce, especially in developing countries. In this report, we examined the dynamics of M.

TB remains a challenging disease to control worldwide. Nanoparticles have been used as drug carriers to deliver high concentrations of antibiotics directly to the site of infection, reducing the duration of treatment along with any side effects of off-target toxicities after systemic exposure to the antibiotics. Herein we have developed a drug delivery platform where gold nanorods (AuNRs) are conjugated to rifampicin (RF), which is released after uptake into macrophage cells (RAW264.
