In vitro, M. tb drives p38 phosphorylation. p38 inhibition suppresses M. tb-dependent MMP-1 secretion by 57.8% and concurrently increases secretion of its specific inhibitor TIMP-1 by 243.7%, demonstrating that p38 activity regulates matrix degradation by macrophages. p38 signals downstream to the cyclooxygenase 2/PGE(2) pathway. p-Aminosalicyclic acid, an agent used to treat drug-resistant tuberculosis, inhibits M. tb-driven MMP-1 but not MMP-7 gene expression and secretion.

Performance characteristics of the assay for TB and RIF resistance detection were calculated using culture and phenotypical DST results as a gold standard.
The mRNA levels of FOXP3 and the proportion of circulating CD4+ CD25+ FOXP3+ Treg cells were increased in multiplicitous drug‑resistant tuberculosis patients compared with those in healthy controls and patients with latent tuberculosis (TB) infection (LTBI) (P<0.001).

We reviewed 994 LPA (Hain MTBDRplus) results at the TB reference laboratory in KwaZulu-Natal to determine the frequency of mutations in either katG or the inhA promoter.
The successful detection of an rpoB gene mutation and two mabA-inhA promoter region mutations while simultaneously differentiating a TB-causing mycobacteria from a non-TB bacteria was accomplished using the optimum conditions of 4.5% (w/v) PDMA in a PDMA coated capillary at 20°C using a separation voltage of 278 V/cm.
Bedaquiline is a new drug of the diarylquinoline class that has proven to be clinically effective against drug-resistant tuberculosis, but has a cardiac liability (prolongation of the QT interval) due to its potent inhibition of the cardiac potassium channel protein hERG.

Patient sputum samples underwent DST for first and second line TB drugs using 2 growth-based (MGIT, MODS) and 2 molecular (Pyrosequencing [PSQ], line-probe assays [LPA]) assays.

The Abbott RealTime MTB (Abbott-RT) and Abbott RealTime MTB RIF/INH Resistance (Abbott-RIF/INH) assays have been introduced for the detection of tuberculosis (TB) and drug-resistant tuberculosis (DR-TB).
Patients at elevated risk of drug-resistant tuberculosis (TB) are prioritized for Xpert(®) MTB/RIF testing; however, the clinical usefulness of the test in this population is understudied.
To evaluate the performance of Xpert(®) MTB/RIF assay for an early diagnosis of TB and detection of rifampicin (RIF) resistance in routine settings in Lithuania.
