Abstract

Previous studies in murine models, including those using the β2 microglobulin knockout mouse, have suggested an important role for CD8+ T cells in host defense to Mycobacterium tuberculosis (Mtb). At present, little is understood about these cells in the human immune response to tuberculosis. This report demonstrates the existence of human Mtb-reactive CD8+ T cells. These cells are present preferentially in persons infected with Mtb and produce interferon γ in response to stimulation with Mtb-infected target cells. Recognition of Mtb-infected cells by these CD8+ T cells is restricted neither by the major histocompatibility complex (MHC) class I A, B, or C alleles nor by CD1, although it is inhibited by anti–MHC class I antibody. The Mtb-specific CD8+ T cells recognize an antigen which is generated in the proteasome, but which does not require transport through the Golgi-ER. The data suggest the possible use of nonpolymorphic MHC class Ib antigen presenting structures other than CD1.

Figure 1 CD8+ T cell line produces IFN-γ in response to Mtb-infected DCs. A CD8+ T cell line was generated from an Mtb-infected individual using infected DCs as described in Materials and Methods. On day 11, T cell lines were assayed by stimulation with Mtb-infected DCs, and supernatants were collected after 18–24 h. Data represents the mean of triplicate determinations of IFN-γ as determined by ELISA. In this and subsequent experiments, the SD is <5% of the mean.

Figure 2 Mtb-reactive CD8+ CTL are found preferentially in individuals infected with Mtb. Mtb-reactive T cell lines were generated and assayed as described in Materials and Methods. Lines were generated from five individuals with evidence of Mtb infection (PPD > 15 mm), and from six individuals with no evidence of Mtb infection (PPD < 5 mm; no history of bacillus Calmette-Guérin vaccination) in three separate experiments. Stimulation index = (Experimental IFN-γ)/(Control IFN-γ). Each tick represents 5 SI units. Positive responses are defined as SI > 5.

Figure 3 Reciprocal specificity of Mtb-reactive and HIV gp24–reactive T cells. 5 × 104 Mtb-reactive CD8+ T cell clones (23 and 29) and an HLA-B44–restricted HIV p24-specific CD8+ T cells (clone 10D10-82) were incubated with 3 × 104 DCs (autologous to clones 23 and 29; B44-positive) that had been treated for 18 h with Mtb, HLA-B44–restricted HIV p24 peptide 103 (303–322), or LPS (5 μg/ml). Supernatants were collected after 18 h and assessed for the presence of IFN-γ by ELISA. Each tick represents 1000 pg/ml. These data are representative of three experiments.

Figure 4 CD8+ T cell clones recognize M. bovis but not M. avium. CD8+ T cell clone 23 was stimulated with autologous DCs infected with varying numbers of either Mtb (H37Rv), M. bovis, or M. avium. After 18 h, supernatants were collected and assessed for the presence of IFN-γ by ELISA.

Figure 5 Mtb-specific CD8+ T cells are not restricted by a unique HLA-A, -B, or -C allele. CD8+ T cell clones 23 and 29 were stimulated with various DCs that had been Mtb infected or not (control) and fixed with 1% paraformaldahyde before addition to culture. DCs from different HLA-typed donors were used as indicated where D160 is autologous to the clones tested. After 18 h, supernatants were collected and assessed for the presence of IFN-γ by ELISA. This experiment is representative of three such experiments.

Figure 6 Anti HLA class I antibody inhibits T cell–dependent generation of IFN-γ. CD8+ T cell clones 23 and 29 were stimulated with Mtb-infected or control DCs in the presence of anti–MHC class I (W6/32; 2 μg/ml), anti–MHC class II (L243; 2 μg/ml), or IgG2a isotype control antibody (2 μg/ml), added at the beginning of the assay. After 18 h, supernatants were collected and assessed for the presence of IFN-γ by ELISA.

Figure 7 Effect of metabolic inhibitors on presentation of Mtb-derived antigen. (A) CD8+ T cell clones 23 and 29 were stimulated with DCs that had been preincubated with metabolic inhibitors, lactacystin (proteasomal degradation; 40 μM), brefeldin A (Golgi-ER transport; 10 μg/ml), chloroquine (endosomal acidification; 100 μM), or cytochalasin D (phagocytosis; 10 μg/ml) for 1 h before the addition of Mtb, and subsequently fixed in 1% paraformaldehyde after 18 h of infection. After 18 h, supernatants were collected and assessed for the presence of IFN-γ by ELISA. This experiment is representative of three such experiments. (B) An influenza matrix peptide–reactive CTL clone was stimulated with DCs that had been preincubated with metabolic inhibitors lactacystin or brefeldin A for 1 h before the addition of live influenza A virus and fixed after 18 h of infection. In the second graph, a PPD-reactive CD4+ T cell clone was stimulated with the APCs described in A. After 18 h, supernatants were collected and assessed for the presence of IFN-γ by ELISA. This experiment is representative of two such experiments.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
