Lymphatic tissue fibrosis is associated with reduced numbers of naive CD4+ T cells in human immunodeficiency virus type 1 infection.
Contrary to CD4+ T lymphocytopenia described for acute CMV mononucleosis, 31 CMV asymptomatic carriers showed a normal count of CD4+ T cells, on average 1.
At least 50,000 CD8+ T cells were acquired for the analysis by using FacsAria I flow cytometer (BD Immunocytometry Systems, San Jose, CA, USA), in all cases a greater number of CD4+ T cells was acquired.
The immunophenotyping of the lymphocytes, especially CD4+ T cells from peripheral blood is being used to assess the extent of immune dysfunction in the primary and secondary immunodeficiency, chronic infectious diseases and various cancers such as Hodgkin's disease, lymphoma, etc.
The first phase occurs during primary HIV infection and the early part of chronic infection when there is substantial depletion of memory (CCR5+) CD4+ T cells and disruption of the structure and function of secondary lymphoid tissues, especially the gut-associated lymphoid tissue (GALT) of the intestinal tract [1-4].
Latent infection of CD4+ T cells provides a mechanism for lifelong persistence of HIV-1, even in patients on effective combination therapy.
Enumeration of CD4+ T cells constitutes an essential biological indicator in the clinical follow up of patients infected with HIV-1.
A single cycle (3 subcutaneous injections) induced a rapid and sustained increase of CD4+ and CD8+ T cells, with most patients treated with 20 og/kg of CYT107 reaching CD4+ T cells counts > 500 cells/oL at W12
The vaccinated animals had good CTL (cytotoxic T lymphocyte) response after infection, stable CD4+ counts (T-cell counts), and CD4+ T cells that responded specifically to the infecting virus.
The primary endpoint was to determine whether the LHRH agonist could induce renewed thymic function and output of new naive CD4+ T cells (which are required for all immune responses), compared to similar patients not receiving the LHRH.
REMUNE(R)'s effect on immune reconstitution as further evidenced by an augmented serum concentration of IL-7 and increases in naive CD4+ T cells suggests a possible mode of action via stimulation of thymus function.
Data from three separate study sites showed that results obtained using the Guava EasyCD4(TM) and EasyCD8(TM) Assays for the enumeration of Human CD4+ T cells and CD8+ T cells showed excellent correlation with the standard, clinically approved BD MultiTEST(TM) (flow cytometry) assay.
