245 MICROASSAY FOR IMMUNOPHENOTYPING OF INFANT LYMPHOCYTE SUBPOPULATIONS

Immunophenotyping of blood lymphocytes in childhood. Reference values for lymphocyte subpopulations.

OBJECTIVE Immunophenotyping of blood lymphocytes is an important tool in the diagnosis of hematologic and immunologic disorders. Because of maturation and expansion of the immune system in the first years of life, the relative and the absolute size of lymphocyte subpopulations vary during childhood. Therefore we wished to obtain reference values for the relative and the absolute size of all rel...

ALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Immunophenotyping of Lymphocyte Subpopulations and pre-inflammatory mediators in neonatal sepsis

Objective: Sepsis is one of the major causes of neonatal morbidity and mortality. The present study was designed to elucidate the changes in the lymphocyte subsets and in the pre-inflammatory mediators; IL-6 and IL-1b in full-term neonates with sepsis Patients and methods: A prospective study was carried out at the neonatology intensive care unit of Cairo University in the period from June 2007...

Heterogeneity of Lymphocyte Subpopulations

or very minimal in all three, including cell-mediated responses in vivo; the in vitro proliferative response to mitogens, allogeneic cells, or antigens; effector cell function in lymphocyte-antibody lymphocytolytic interaction assays; and in vitro synthesis of IgG, IgA, and IgM. In contrast, mononuclear cells from one of the infants were tested and found capable of lysing both human and chicken...
