SSEA-4 antigen can be mainly found in embryos and embryonic stem cells. However, its expression has been observed also adult progenitor cells, or even some differentiated Moreover, we a considerable number of positive (SSEA-4+) cells within the rabbit peripheral blood bone marrow mononuclear (PBMCs BMMCs) our previous study. Since no information about such anywhere literature, aim this study wa...

The ratio of patients with RPR constant positive more than 2 years despite receiving standard syphilis treatment has been reported to be 11.54%~31.3%. The current interpretations on this phenomenon are cellular immune function restrained and the existence of neurosyphilis or asymptomatic neurosyphilis. We conducted this study to detect the treponemal antibody in cerebrospinal fluid (CSF) and ly...

AIMS To investigate the effects of longer term corticosteroid treatment on circulating lymphocyte subsets. METHODS Prednisolone (20 mg daily) was given to 12 healthy volunteers in a single morning dose for three days. Circulating lymphocyte subsets were measured by flow cytometry after whole blood lysis. RESULTS Seven hours after the first dose of prednisolone there was a significant fall i...

In contrast to conventional T cells, natural killer (NK) 1.1+ T cell receptor (TCR)-alpha/beta+ (NK1+T) cells, NK cells, and intestinal intraepithelial lymphocytes (IELs) bearing CD8-alpha/alpha chains constitutively express the interleukin (IL)-2 receptor (R)beta/15Rbeta chain. Recent studies have indicated that IL-2Rbeta/15Rbeta chain is required for the development of these lymphocyte subset...

Migratory properties of normal peripheral blood lymphocyte subsets were studied with a 3-D collagen gel model. Both the T and B subsets entered the gel at the same rate, but once inside the T subsets migrated significantly faster than the B subsets. In the T subsets, both the T-helper and T-suppressor cells entered the gel at the same rate, but the former migrated significantly faster once insi...

immunophenotyping of lymphocytes is very essential for evaluation of immune system. due  to  the  effect  of  environmental  factors  and  ethnical diversity on  immune  system, establishment of an internal normal range of lymphocyte subsets is a necessity for each population.  the  aim  of  this  study  was  to  determine  the  normal  range  of  t  and  b lymphocytes, and nk cells in normal i...
