In addition, PB CD27(+) memory B cells were 2-fold higher and serum SIV antibodies increased significantly after IL-21 administration.

After stimulation of PBMC from TT-vaccinated donors TT-specific proliferated B cells were detected in high frequencies and showed a plasmablast-typical CD20(low) CD27(high) phenotype with only low frequencies expressing CD138 (= Syndecan-1).

B19-specific T cells developed and maintained an activated CD38+ phenotype, with strong expression of perforin and CD57 and downregulation of CD28 and CD27.

These CD8+ T lymphocytes rapidly differentiated to memory cells, defined on the basis of their cytokine profile and expression of CD62L and CD27.

Grossly, twice as many TT-specific CD4+ T-cell clones, ex vivo derived from the CCR7+/- CD69+ interleukin-2-positive (IL-2+) CD4+ subsets, belonged to the central memory (T(CM); CD62L+ CD27+ CCR7+) compared to the effector memory population (T(EM); CD62L- CD27- CCR7-).

In adults, the expression of the T cell differentiation marker CD27 on virus-specific CD8+ T cells decreased after LAIV but increased after TIV.

Further phenotypic analysis revealed that the acquisition of KLRG1 among effector subpopulations correlated with the down-regulation of both IL-7R and CD27, suggesting that KLRG1 marks dominant, end-stage effector cells.

In healthy individuals, the human peripheral blood CD27(+) B cell pool consists of two subsets defined by the expression, or lack thereof, of the CD45 isoform B220.

The AICD expression, along with CD86 expression, by CD27(+)B220(+) suggests these cells are of germinal center origin.

SUMMARY: After binding its natural ligand cluster of differentiation 70 (CD70), CD27, a tumor necrosis factor receptor (TNFR)-associated factor-binding member of the TNFR family, regulates cellular activity in subsets of T, B, and natural killer cells as well as hematopoietic progenitor cells.

In normal immune responses, CD27 signaling appears to be limited predominantly by the restricted expression of CD70, which is only transiently expressed by cells of the immune system upon activation.

CD4 T cells expressing IFN-gamma, IL-2, or both expressed a CD45RA(-)CCR7(-)CD27(+/-) effector memory phenotype.

Mycobacteria-specific CD8 T cells expressed mostly IFN-gamma in all groups of children; these cells expressed CD45RA(-)CCR7(-)CD27(+/-) or CD45RA(+)CCR7(-)CD27(+/-) effector memory phenotypes.

Sorted human CD19+CD27+ B cells were retrovirally transduced with the human B cell lymphoma (BCL)-6 and BCL-XL genes, and subsequently cultured in the presence of CD40-ligand and IL-21.

With strongly replicating (i.e., virulent) VACV, the TNFR family costimulatory receptors OX40 (also known as CD134) and CD27 were engaged and promoted the generation of high numbers of memory CD8+ T cells, which protected against a lethal virus challenge in the absence of other mechanisms, including antibody and help from CD4+ T cells.
|

|
In contrast, weakly replicating (i.e., low-virulence) VACV strains were poor at eliciting protective CD8+ T cell memory, as only the Ig family costimulatory receptor CD28 was engaged, and not OX40 or CD27.

CD8(+) cells from the vHIV individuals exhibited the highest HIV-suppressing activity and had elevated frequencies of CD45RA(-) CD27(+) and PD-1(+) (CD279(+)) cells.

|
Ad5-specific CD4(+) T cells were primarily monofunctional CD4(+) T cells that produced IL-2, IFN-gamma or TNFalpha and expressed the memory markers CD27 and CD45RO.
|

|
In contrast, Ad5-specific CD8(+) T cells were more polyfunctional, expressing effector-like combinations of IFN-gamma, MIP1alpha and perforin, and generally lacked CD27 and CD45RO expression.

We describe an extensive effort to optimize and validate quantitatively an in vitro T-cell culture method by determining the phenotype and function of both CD4(+) and CD8(+) T cells, including measurement of the phenotype markers CCR7, CD45RA, CD28 and CD27 and the functional markers interferon (IFN)-gamma, interleukin (IL)-2, macrophage inflammatory protein (MIP)-1beta, tumor necrosis factor (TNF)-alpha and CD107a.

However, after direct TCR stimulation, naive CD4 T cells from HCV-infected patients had altered up-regulation of KI67 and CD25 and less CD27 expression.

Polychromatic cytometry analysis indicated that the virus-specific T cells from the severe group tended to be a central memory phenotype (CD27(+)/CD45RO(+)) with a significantly higher frequency of polyfunctional CD4(+) T cells producing IFN-gamma, TNF-alpha, and IL-2, and CD8(+) T cells producing IFN-gamma, TNF-alpha, and CD107a (degranulation), as compared with the mild-moderate group.
