Immunological parameters including serum IgG, IgA and IgM, lymphocyte phenotypes (CD3, CD4, CD8, HLA-DR+CD3-), natural killer cell activity and lymphocyte proliferation with phytohaemagglutinin were assessed in 10 children on continuous ambulatory peritoneal dialysis (CAPD) and 10 control subjects.

The serum IgG level was statistically lower in the CAPD group than in the control group (P less than 0.01), but there was no difference in the percentage of HLA-DR+CD3- cells and in the ratio of CD4 to CD8 between the two groups.

CD1 and CD8 antigens were not expressed on the proliferative TLC.

|
CD2, CD3, CD4, and CD5 antigens were homogeneously expressed on all TLC in contrast to CD6 and CD7 antigens which were present on only a fraction of the cells in a given TLC.
|

|
Surface marker analysis revealed that the expression of CD2 to CD7 antigens (and also CD25) may be modified following incubation of the TLC with TPA or sodium butyrate but not with 5-azacytidine.

Sixteen of the resulting T-lymphocyte cell lines (from the S19 and S19+IL-2 groups) were tested through indirect immunofluorescence for expression of cell surface markers CD2, CD4, CD6, CD8, major histocompatibility complex (MHC) Class II molecules and a marker expressed on a subset of helper T-lymphocytes (Th) as well as sIgM, CD1 and a MHC Class II+ monocyte/macrophage marker.

However, two cell lines contained significant populations (> 80%) of CD2-, CD4-, CD6-, CD8- cells that were both responsive to exogenous rBoIL-2 and were capable of exhibiting antigen-induced LP responses.

In this study, the T cell composition of blood lymphocytes (CD4(+)CD8(+); CD4(+)CD8(-); CD4(-)CD8(+); CD8(+)TcR1(+); CD8(-)TcR1(+), CD8(+)TcR1(-)) after oral administration of the non-attenuated S. typhimurium wild-type strain 421 (infection) or the attenuated vaccine strain Salmonella vac((R)) T (immunization) to day-old chicks was investigated and compared with non-treated chickens by flow cytofluorometry.

Additionally, the occurrence of T cell sub-populations (CD4(+); CD8(+); TcR1(+)(gammadelta); TcR2(+)(alphabeta(1))) in ceca, spleen and bursa of Fabricius of the birds was studied immunohistologically.

The CD4 to CD8 cell ratio was about 3:1 in infected animals on day 5 of age.

The frequencies of CD8+ and CD4+ T cells responsive to cytomegalovirus (CMV), varicella zoster virus (VZV), and tetanus in antigen-activated whole blood were determined by flow cytometric analysis of CD69, TNF alpha, IFN gamma and IL-4 expression.
|

|
In spite of a continuously reduced CD4 to CD8 ratio after transplantation, recovery of CD4+ T cells usually occurred prior to CD8+ recovery and often to a higher level.

The present work demonstrated that the CpG oligonucleotides (CpG-ODN) 2216, D32 and D19 induce high amounts of interferon-alpha (IFN-alpha), tumour-necrosis factor-alpha (TNF-alpha) and interleukin (IL)-12 in porcine peripheral blood mononuclear cells (PBMCs).

These cells did not express CD6, CD8 or CD45RA.

Importantly, monocyte-derived DC did not respond to CpG-ODN by secretion of IFN-alpha or TNF-alpha or by the up-regulation of costimulatory molecule expression.

Such immunity appears to be mediated by the generation of phenotypic and functional CD8+ CTL through CD4+ to CD8+ conversion, which we have demonstrated at the single cell level.

CD4+ to CD8+ conversion depends on effective in vivo activation and is promoted by CD4+ T cell proliferation.

The ratio of tuberculin-specific CD4 to CD8 cells in short-term cultures were significantly (P less than 0.05) higher in the vaccinees.

For instance, the K5 modulator of immune recognition (MIR2) from Kaposi sarcoma-associated herpesvirus prevents activation of cytotoxic T cells, natural killer cells, and natural killer T cells by downregulating major histocompatibility complex (MHC) class I molecules, the MHC-like molecule CD1, the cell adhesion molecules ICAM-1 and PECAM, and the co-stimulatory molecule B7.2.

Mass spectrometric protein identification revealed four proteins that were consistently underrepresented in the plasma membrane of K5 expression cells: MHC I (as expected), bone marrow stromal antigen 2 (BST-2, CD316), activated leukocyte cell adhesion molecule (ALCAM, CD166) and Syntaxin-4.

Since ALCAM is the ligand for CD6, a member of the immunological synapse of T cells, its removal by viral immune modulators implies a role for CD6 in the recognition of pathogens by T cells.
