Murine reconstitution assays were used to investigate the effects of recombinant human interleukin-7 (rhIL-7) on myeloid and lymphoid precursors and on bone marrow engraftment. Reconstitution with bone marrow from rhIL-7-treated mice results in a 3.4-fold decrease in total colony-forming unit-spleen (CFU-S) activity (day 9) and an 18.1- and 11.9-fold decrease in its ability to generate thymocyt...

BACKGROUND The degree of immune reconstitution achieved in response to suppressive ART is associated with baseline individual characteristics, such as pre-treatment CD4 count, levels of viral replication, cellular activation, choice of treatment regimen and gender. However, the combined effect of these variables on long-term CD4 recovery remains elusive, and no single variable predicts treatmen...

BACKGROUND Antiretroviral therapy (ART) partially corrects immune dysfunction associated with HIV infection. The levels of T-cell immune activation and exhaustion after long-term, suppressive ART and their correlation with CD4 T-cell count reconstitution among ART-treated patients in African cohorts have not been extensively evaluated. METHODS T-cell activation (CD38+HLA-DR+) and immune exhau...

Treatment of HIV-infected patients with highly active antiretroviral therapy (HAART) usually results in diminished viral replication, increasing CD4⁺ cell counts, a reversal of most immunological disturbances, and a reduction in risk of morbidity and mortality. However, approximately 20% of all HIV-infected patients do not achieve optimal immune reconstitution despite suppression of viral repli...

Meningococcal and gonococcal outer membrane proteins were reconstituted into liposomes using detergent-mediated dialysis. The detergents octyl glucopyranoside (OGP), sodium cholate and Empigen BB were compared with respect to efficiency of detergent removal and protein incorporation. The rate of OGP removal was greater than for cholate during dialysis. Isopycnic density gradient centrifugation ...

The reconstitution of apo-glucose oxidase (apo-GOx) on single-walled carbon nanotubes (SWNTs) functionalized with the cofactor, flavin adenine dinucleotide (FAD), greatly improved electron transfer turnover rate of the redox reactions in glucose sensing with glucose sensors. The research reported here is aimed to better understand molecular details of affection of the charging SWNT to the confo...

Blood cells transplantation is largely replacing bone marrow transplantation because engraftment is more rapid. This accelerated engraftment is thought to be mediated by relatively mature committed hematopoietic progenitor cells. Herein, we have used a modified rhodamine (Rho) staining procedure to identify and purify Rho+/++ (dull/bright) and Rho- (negative) subpopulations of hematopoietic pro...

Cryptococcosis is the most common cause of meningitis in Africa due to the high burden of HIV. Immune reconstitution inflammatory syndrome (IRIS) is a frequent and deadly complication of cryptococcal meningitis. We report a fatal case of cryptococcal-IRIS in a pregnant woman that began after starting antiretroviral therapy (unmasking IRIS) and markedly worsened postpartum after delivery (parado...

Human immunodeficiency virus (HIV) associated thrombocytopenia was commonly encountered in the era prior to the advent of antiretroviral therapy (ART). With the widespread use of ART, its incidence has significantly declined. Immune reconstitution inflammatory syndrome (IRIS) is an immune dysregulation phenomenon that reveals itself clinically as paradoxical deterioration after the commencement...

Indian J Dermatol Venereol Leprol | May-June 2008 | Vol 74 | Issue 3 does not have any effect after 72 hrs, the steroids given early and for a short duration may help improve the prognosis. Since cyclosporine is reported to be effective in TEN by interrupting the disease progression and decreasing the time taken for complete re-epithelization, we feel that the combination of initial high dose o...
