A 2-Dose AERAS-402 Regimen Boosts CD8+ Polyfunctionality in HIV-Negative, BCG-Vaccinated Recipients
Sivakumaran, Dhanasekaran; Blatner, Gretta; Bakken, Rasmus; Hokey, David A.; Ritz, Christian; Jenum, Synne; Grewal, Harleen (Journal article; Peer reviewed, 2021)Despite the widespread use of BCG, tuberculosis (TB) remains a global threat. Existing vaccine candidates in clinical trials are designed to replace or boost BCG which does not provide satisfying long-term protection. ... -
Added Value of IP-10 as a Read-Out of Mycobacterium tuberculosis. Specific Immunity in Young Children
Jenum, Synne; Sivakumaran, Dhanasekaran; Ritz, Christian; Macaden, R; Doherty, TM; Grewal, Harleen; TB Trials Study, Group (Peer reviewed; Journal article, 2016)We have explored the added value of interferon-γ (IFNγ)– inducible protein 10 as a read-out of Mycobacterium tuberculosis–specific immunity in young Indian children, where the sensitivity of the IFNγ release assays for ... -
Approaching a diagnostic point-of-care test for pediatric tuberculosis through evaluation of immune biomarkers across the clinical disease spectrum
Jenum, Synne; Sivakumaran, Dhanasekaran; Lodha, Rakesh; Mukherjee, Aparna; Saini, Deepak Kumar; Singh, Sarman; Singh, Varinder; Medigeshi, Guruprasad; Haks, Marielle C.; Ottenhoff, Tom H.M.; Doherty, Timothy Mark; Kabra, Sushil K.; Ritz, Christian; Grewal, Harleen (Peer reviewed; Journal article, 2016-01-04)The World Health Organization (WHO) calls for an accurate, rapid, and simple point-of-care (POC) test for the diagnosis of pediatric tuberculosis (TB) in order to make progress “Towards Zero Deaths”. Whereas the sensitivity ... -
BLR1 and FCGR1A transcripts in peripheral blood associate with the extent of intrathoracic tuberculosis in children and predict treatment outcome
