The lymphocytes in the perivascular foci of tuberculin skin tests have a similar CD4:CD8 ratio to those in the peripheral blood, suggesting that these subsets do not show bias in their initial emigration. By contrast, the diffusely infiltrating lymphocytes show a relative preponderance of CD4 cells which is progressively greater in successive 250 micron layers into the dermis. A generally similar pattern is seen in healthy controls and in patients with untreated pulmonary tuberculosis, treated leprosy, haemophilia A and chronic obstructive lung disease (COLD) patients treated with prednisolone, but the gradient of increasing CD4:CD8 ratio with depth into the dermis is significantly less steep in patients with tuberculosis, haemophilia and prednisolone-treated COLD than in the healthy controls. Selective migration results in a relative preponderance of CD4 cells in the diffuse infiltrate and it is suggested that this is a mechanism likely to potentiate defensive reaction to Mycobacterium tuberculosis: any deficiency in selective migration may make immunological defences less effective and so contribute to the chronicity of the lesions of tuberculosis.
