    Cytokine production by human colonic intraepithelial lymphocytes in controls and ulcerative colitis
    (Hindawi Publishing Cooperation, 1994) Hoang, P.; Dalton, H.R.; de Silva, H.J.; Jewell, D.P.
    Using an ELISA technique, concentrations of gamma-interferon and interleukin-2 were assayed in the supernatants of colonic intraepithelial lymphocytes cultured with or without phytohaemagglutinin (PHA). IntraepitheHal lymphocytes produced low concentrations of gamma-interferon and interleukin-2 when stimulated with PHA, but significantly more than when unstimulated (p < 0.05). There was no difference in production of these cytokines by IEL from control or inflammatory bowel disease.

    Immune activation during cerebellar dysfunction following Plasmodium falciparum malaria
    (Oxford University Press, 1992) de Silva, H.J.; Hoang, P.; Dalton, H.; de Silva, N.R.; Jewell, D.P.; Peiris, J.B.
    Evidence for immune activation was investigated in 12 patients with a rare syndrome of self-limiting, delayed onset cerebellar dysfunction following an attack of falciparum malaria which occurred 18-26 d previously. Concentrations of tumour necrosis factor, interleukin 6 and interleukin 2 were all significantly higher in serum samples of patients during cerebellar ataxia than in recovery sera and in the sera of 8 patients who did not develop delayed cerebellar dysfunction following an attack of falciparum malaria. Cytokine concentrations in the cerebrospinal fluid were also significantly higher in ataxic patients than in controls. These findings suggest that immunological mechanisms may play a role in delayed cerebellar dysfunction following falciparum malaria.
