Multicolor Flow Cytometric Analyses of CD4(+) T Cell Responses to Mycobacterium tuberculosis-Related Latent Antigens.

Multicolor Flow Cytometric Analyses of CD4(+) T Cell Responses to Mycobacterium tuberculosis-Related Latent Antigens. Jpn J Infect Dis. 2013;66(3):207-15 Authors: Yamashita Y, Hoshino Y, Oka M, Matsumoto S, Ariga H, Nagai H, Makino M, Ariyoshi K, Tsunetsugu-Yokota Y Abstract Although IFN-γ release assays (IGRAs) provide increased specificity over tuberculin skin tests, the early and sensitive detection of reactivation of latently infected Mycobacterium tuberculosis is required to control tuberculosis (TB). Recently, a multicolor flow cytometry has been developed to study CD4(+) T cell cytokine responses (IFN-γ/IL-2/TNF-α) to purified protein derivatives (PPD) and M. tuberculosis-specific antigens (ESAT-6/CFP-10) and provided useful information regarding anti-TB immunity. However, the diagnostic relevancy remains uncertain. Here, we analyzed three additional CD4(+) T cell cytokine responses (IL-10/IL-13/IL-17) to latent mycobacterial antigens (α-crystallin, methylated heparin-binding hemagglutinin [HBHA], and mycobacterial DNA-binding protein 1 [MDP-1]) as well as PPD and ESAT-6/CFP-10 in 12 IGRA(+) TB cases and 8 healthy controls. No significant difference in IFN-γ response was observed between TB cases and controls, which was likely due to the high variation among the individuals. However, we found a significant increase over healthy controls in (i) the IL-2 response to HBHA in recovery stage TB cases, (ii) the number of M. tube...

ConclusionThis study demonstrates that ESAT6 bound with TLR2 can activate iNOS/NO and ROS signalings to reduce the trimethylation of H3K27 resulting in the increment of EMMMs expression that is beneficial to the transition of macrophages into epithelioid macrophages. However, hypoxia can inhibit this transition event. This study has provided new evidence of pathogenesis of granuloma caused by Mtb and also proposed new ideas for the treatment of TB.

Bilateral lung parenchymal involvement is seen in infective as well as noninfective conditions, appearing as focal or diffuse lung disease. PET/CT with FDG helps in characterization (increased glucose utilization is seen by both inflammatory and neoplastic cells). In this article, we describe the spectrum of patterns of FDG uptake and associated CT changes involving bilateral lung parenchyma. Benign conditions described are aspiration pneumonia; pulmonary toxicity by bleomycin; infections, namely, sarcoidosis, miliary pulmonary tuberculosis, and pulmonary nocardiosis; and inflammatory conditions such as pulmonary Langerhan...

CONCLUSION: During the last century, AADRs among males declined more slowly than among females. Although the gap diminished in recent decades, exploration of social and behavioral factors may inform interventions that could further reduce death rates among males.

Authors: Cerrone M, Bracchi M, Wasserman S, Pozniak A, Meintjes G, Cohen K, Wilkinson RJ Abstract Introduction: Antiretroviral and anti-tuberculosis (TB) drugs are often co-administered in people living with HIV (PLWH). Early initiation of antiretroviral therapy (ART) during TB treatment improves survival in patients with advanced HIV disease. However, safety concerns related to clinically significant changes in drug exposure resulting from drug-drug interactions, development of overlapping toxicities and specific challenges related to co-administration during pregnancy represent barriers to successful combined tre...

Publication date: 15 February 2020Source: Journal of Molecular Structure, Volume 1202Author(s): Jamelah S. Al-Otaibi, Y. Sheena Mary, Stevan Armaković, Renjith ThomasAbstractThree cocrystals of pyrazinamide (PYZ) with 2,4-dihydroxy benzoic acid (2,4HBA-PYZ), 2,6-dihydroxybenzoic acid (2,6HBA-PYZ) and 3,5-dihydroxybenzoic acid (3,5HBA-PYZ) are investigated by computational simulations. DFT calculations have been performed in order to understand the reactive properties of molecules that constitute the cocrystals. These calculations were followed by symmetry-adapted perturbation theory (SAPT) simulations to understand the in...

In this study we analysed the clinical profile of meningoencephalitis and its clinical outcome. METHODS: Fifty adults diagnosed with meningoencephalitis from July 2014 to July 2015 in a tertiary care hospital in South India were studied prospectively and their clinical presentation, aetiology and outcome were analysed. RESULTS: Among 50 patients, 33 (66%) were male; 39 (78%) were

Conclusions: AEs were common, but not more frequent or severe among MDR-TB/HIV co-infected participants receiving concurrent antiretroviral therapy. Given the favorable treatment outcomes associated with concurrent treatment, antiretroviral therapy initiation should not be delayed in MDR-TB patients with HIV-coinfection.
