Salmon, M, Kitas, G D, Gaston, J S, Bacon, P A

This study investigated the production of, and response to, the lymphokine interleukin-2 (IL-2) by functional subsets of human CD4+ T lymphocytes. Fresh peripheral blood mononuclear cells (PBMC) were...

Identification of T-cell stimulatory antigens of Chlamydia trachomatis using synovial fluid-derived T-cell clones.

Hassell, A B, Reynolds, D J, Deacon, M, Gaston, J S, Pearce, J H

Chlamydia trachomatis is a major cause of sexually transmitted disease, infertility and reactive arthritis in the Western world, and of trachoma in the developing world. There is evidence that the...

The abnormal cytotoxic T cell response to Epstein-Barr virus in rheumatoid arthritis is correlated with disease activity and occurs in other arthropathies.

Gaston, J S, Rickinson, A B, Yao, Q Y, Epstein, M A

The cytotoxic T cell response to Epstein-Barr virus as measured by the regression assay was found to be impaired in a group of patients with active rheumatoid arthritis (RA). When these patients...

Acute confusional state and hyponatraemia due to inappropriate antidiuretic hormone secretion in polyarteritis nodosa.

Gaston, J S, Scott, D G, Bacon, P A

An acute confusional state, which developed in a patient with polyarteritis nodosa (PAN), proved to be secondary to inappropriate secretion of antidiuretic hormone and consequent hyponatraemia. This...

Churg-Strauss vasculitis and ascaris infection.

Chauhan, A, Scott, D G, Neuberger, J, Gaston, J S, Bacon, P A

A patient with Churg-Strauss vasculitis presenting with mononeuritis multiplex, who developed obstructive jaundice, is described. On investigation the jaundice proved to be due to ascaris...

Lysis of human macrophages by cytolytic CD4+ T cells fails to affect survival of intracellular Mycobacterium bovis-bacille Calmette-Guérin (BCG).

Fazal, N, Lammas, D A, Rahelu, M, Pithie, A D, Gaston, J S, Kumararatne, D S

Human CD4+, mycobacteria-specific, cytolytic T cell clones were used to lyse BCG-infected macrophages, and the effect on the subsequent growth and viability of the organisms was examined. The...

Synovial fluid antigen-presenting cells unmask peripheral blood T cell responses to bacterial antigens in inflammatory arthritis.

Life, P F, Viner, N J, Bacon, P A, Gaston, J S

We and others have previously shown that synovial fluid (SF) mononuclear cells (MC) from patients with both reactive arthritis and other inflammatory arthritides proliferate in vitro in response to...

Specific lysis of mycobacterial antigen-bearing macrophages by class II MHC-restricted polyclonal T cell lines in healthy donors or patients with tuberculosis.

Kumararatne, D S, Pithie, A S, Drysdale, P, Gaston, J S, Kiessling, R, Iles, P B, ...

The cytolytic capacity of mycobacterial antigen-stimulated peripheral blood mononuclear cells, from healthy Mantoux-positive volunteers and from patients with tuberculosis was investigated....

Deficient interleukin 2 production in rheumatoid arthritis: association with active disease and systemic complications.

Kitas, G D, Salmon, M, Farr, M, Gaston, J S, Bacon, P A

Interleukin 2 (IL-2) production and proliferative responses of peripheral blood mononuclear cells (PBMC) stimulated with three concentrations of PHA were measured in 75 patients with rheumatoid...

Synovial T lymphocyte recognition of organisms that trigger reactive arthritis.

Gaston, J S, Life, P F, Granfors, K, Merilahti-Palo, R, Bailey, L, Consalvey, S, ...

Reactive arthritis (ReA) is believed to be "triggered' by infection with certain bacteria. When the proliferative responses of mononuclear cells (MC) obtained from the synovial fluid (SF) of ReA...

Disturbance of the Epstein-Barr virus-host balance in rheumatoid arthritis patients: a quantitative study.

Yao, Q Y, Rickinson, A B, Gaston, J S, Epstein, M A

Rheumatoid arthritis (RA), seronegative spondyloarthropathy (SA) and osteoarthritis (OA) patients receiving no steroid or disease-modifying therapy have been monitored, along with healthy controls,...

Mucosal cell-mediated immunity to mycobacterial, enterobacterial and other microbial antigens in inflammatory bowel disease.

Ibbotson, J P, Lowes, J R, Chahal, H, Gaston, J S, Life, P, Kumararatne, D S, ...

Culture studies have suggested that Mycobacterium paratuberculosis may play a role in the aetiology of Crohn's disease. However, evidence of sensitization to mycobacterial antigens amongst patients...

MHC restriction of synovial fluid lymphocyte responses to the triggering organism in reactive arthritis. Absence of a class I-restricted response.

Hassell, A B, Pilling, D, Reynolds, D, Life, P F, Bacon, P A, Gaston, J S

Synovial fluid mononuclear cells (SFMC) from patients with reactive arthritis (ReA) show marked proliferative responses to preparations of the organism triggering the arthritis. Initial studies with...

Synovial fluid antigen-presenting cell function in rheumatoid arthritis.

Viner, N J, Gaston, J S, Bacon, P A
