Wedderburn, Lucy R., Maini, Mala K., Patel, Alka, Beverley, Peter C. L., Woo, Patricia

We have demonstrated a stable expansion of CD8+ T cells in the peripheral blood of a child with chronic arthritis. The expanded TCRBV family (TCRBV14) was enriched for CD57hiCD28– T cells....

T cell responses to peptides covering the gag p24 region of HIV -1 occur in HIV -1 seronegative individuals (1991)

Vyakarnam, Annapurna, Matear, Patricia M., Cranenburg, Charmaine, Michie, Colin, Beverley, Peter C. L., Wahren, Britta, ...

We demonstrate that peptides (16 amino acids long) covering the sequence of the HIV-1 core protein p24 induce significant proliferation in peripheral blood mononuclear cells (PBMC) of several...

Evidence for differential expression of CD45 isoforms by precursors for memory-dependent and independent cytotoxic responses: human CD8 memory CTLp selectively express CD45R0 (UCHL1) (1989)

Merkenschlager, Matthias, Beverley, Peter C. L., MacDonald, Robson

On the basis of differential CD45 expression, human T cells can be separated into approximately reciprocal populations. The mAb UCHL1 detects a 180 kd molecular mass isoform, CD45R0. The CD45RA...

A high-frequency polymorphism in exon 6 of the CD45 tyrosine phosphatase gene (PTPRC) resulting in altered isoform expression

Stanton, Tara, Boxall, Sally, Hirai, Kouzo, Dawes, Ritu, Tonks, Susan, Yasui, Tomoyo, ...

CD45 (leukocyte common) antigen is a hemopoietic cell-specific tyrosine phosphatase essential for antigen receptor-mediated signaling in lymphocytes. The molecule undergoes complex alternative...

Human CD4+ CD25hi Foxp3+ regulatory T cells are derived by rapid turnover of memory populations in vivo

Vukmanovic-Stejic, Milica, Zhang, Yan, Cook, Joanne E., Fletcher, Jean M., McQuaid, Arthur, Masters, Joanne E., ...

While memory T cells are maintained by continuous turnover, it is not clear how human regulatory CD4+CD45RO+CD25hi Foxp3+ T lymphocyte populations persist throughout life. We therefore used deuterium...

CD45 negatively regulates tumour necrosis factor and interleukin-6 production in dendritic cells

Piercy, Jenny, Petrova, Svetla, Tchilian, Elma Z, Beverley, Peter C L

CD45 is known to regulate signalling through many different surface receptors in diverse haemopoietic cell types. Here we report for the first time that CD45−/− bone marrow dendritic cells (BMDC)...

Prolonged exposure of naïve CD8+ T cells to interleukin-7 or interleukin-15 stimulates proliferation without differentiation or loss of telomere length

Wallace, Diana L, Bérard, Marion, Soares, Maria V D, Oldham, Janine, Cook, Joanne E, Akbar, Arne N, ...

Interleukin (IL)-7 and IL-15 are cytokines implicated in homeostatic control of the peripheral CD8 T-cell pool. We compared the effects of IL-7 and IL-15 on survival and proliferation of purified...
