The B lymphocyte-activating factor belonging to TNF superfamily (BAFF) acts on B lymphocytes through BAFF receptor (BAFF-R), the transmembrane activator, calcium modulator, and cyclophilin ligand interactor (TACI), and the B cell maturation antigen (BCMA). Another cytokine, a proliferation-inducing ligand (APRIL), only binds to TACI and BCMA. In this study,(More)
Capsular polysaccharides of encapsulated bacteria are weakly immunogenic T cell-independent type 2 (TI-2) Ags. Recent findings suggest that BAFF system molecules have a critical role in the development of Ab responses against TI-2 Ags. In this study, we investigated the effect of bacterial polysaccharides on B cell responses to BAFF and a(More)
Capsular polysaccharides of encapsulated bacteria do not induce immune response in newborns and the mechanism for this unresponsiveness is not clear. In adults, transmembrane activator and calcium-modulator and cyclophilin [corrected] ligand interactor (TACI) is a TNFR family member molecule with a pivotal role in Ab responses against polysaccharide(More)
BACKGROUND As the number of AIDS cases increases in India, information available among clinicians about the prevalence of opportunistic infections (OIs) is scarce. The aim of the present study was to document the characteristic OIs of HIV-infected North Indian patients along with their CD4+ counts. PATIENTS AND METHODS The study group consisted of(More)
Encapsulated Neisseria meningitidis can invade mucosal barriers and cause systemic diseases. Activation of the innate immune system by conserved meningococcal molecules such as lipooligosaccharides (LOS) is essential for the generation of an effective host immune response. Here we show that the type C capsular polysaccharide of N. meningitidis (MCPS)(More)
This study was designed to evaluate the absolute CD4+ counts and percentages in HIV subtype C infected patients at a tertiary care hospital in northern India. The CD4+ counts of 377 HIV seropositive subjects were estimated by a FACS Calibur (BD) flow cytometer. Dual color immunophenotyping was performed on each sample, which was acquired and analysed using(More)
Individuals with HIV infection are at increased risk for tuberculosis (TB). The altered CD4 T-cell homeostasis induced by HIV infection may play a key role in the development of tuberculosis in HIV-infected patients. In this retrospective analysis, lymphocyte profiles (CD4 and CD8 count) of subjects infected with HIV, with or without TB, were evaluated. The(More)
With the advent and application of standard and sensitive flow cytometry methods, it became essential to establish reference intervals in healthy individuals to demarcate between health and disease. A reference range of lymphocyte populations for normal individuals is important in the diagnosis and prognosis of immunodeficiency diseases like AIDS. We tried(More)
