Project description:Monocytes and granulocytes were isolated from blood of TB patients and household contacts. RNA was isolated and microRNA expression was measured using microarrays.
Project description:Monocytes and granulocytes were isolated from blood of TB patients and household contacts. RNA was isolated and microRNA expression was measured using microarrays. House-hold contacts were matched to TB patients by gender and age. From each subject, two profiles (monocytes and granulocytes) were collected.

Project description:Three complete TMTs for saliva and three complete TMTs for sputum samples from active tuberculosis patients (TB) and their household infected (LTI) and uninfected (nonLTI) contacts.
Parallel Reaction Monitoring (PRM) analysis in sputum samples of infected and uninfected contacts to measure levels of MUC7, CYST, CAH6 and PERL.
Project description:Identification of blood transcriptional biomarkers linked to different phases of tuberculosis. The discovery of a transcriptional signature that distinguishes subclinical TB from incipient TB at baseline could lead to tuberculosis interventions that combat the tuberculosis epidemic in the context of household contacts.
Project description:The overall scope of this study is to find early tuberculosis (TB) candidate protein biomarkers in different TB study groups vs. controls. The identified biomarkers may become the basis of a rapid diagnostic test able to identify active TB earlier than current practice. In addition, the candidate biomarkers may predict which patients are likely to convert from latent infection to active disease. . This project uses plasma and serum samples collected in a long-standing TB household contact study, the Kawempe Community Health Study, conducted in Kampala, Uganda, a TB endemic area. The study utilizes samples from TB index cases and household contacts that were negative for TB at recruitment. A subset of these contacts developed Mtb infection (i.e., their Tuberculin Skin Test (TST) converted to positive) after 3-6 months, and smaller subset developed active TB after 3 months of follow-up. Control patients were still TST negative at 12 months or 24 months of follow-up. This dataset corresponds to the discovery phase of the study.
Project description:Whole blood gene expression profiling from well and malnourished Indian individuals with TB and severely malnourished household contacts with latent TB infection (LTBI). Severe malnutrition was defined as body mass index (BMI) <16. kg/m2 in adults and based on weight-for-height Z scores in children <18 years. Gene expression was measured using RNA-sequencing.
