Dendritic cells induce CD4+ and CD8+ T-cell responses to Mycobacterium bovis and M. avium antigens in Bacille Calmette Guérin vaccinated and nonvaccinated cattle.

We used autologous dendritic cells (DC) infected with Mycobacterium bovis Bacille Calmette Guérin (BCG) or pulsed with purified protein derivative from M. bovis (PPD-B) or M. avium (PPD-A) to assess responses of CD4+, CD8+ and WC1+ gammadelta TCR+ lymphocytes from BCG vaccinated and nonvaccinated cattle.

|
Mycobacteria-specific CD4+ and CD8+, but not WC1+ gammadelta TCR+, memory T lymphocytes were demonstrated in BCG-vaccinated cattle.
|

|
CD4+ and CD8+ lymphocytes proliferated and produced interferon (IFN)-gamma in response to BCG-infected or PPD-B-pulsed DC.
|

|
Proliferative responses were greater for CD4+ than CD8+ lymphocytes, although secretion of IFN-gamma was higher from the CD8+ T cells.
|

|
The findings suggest that immunity to M. bovis induced by BCG vaccination in cattle may involve CD8+ memory T cells which produce IFN-gamma, as well as CD4+ memory T cells.

The IFN-gamma(+) cells included CD4(+) and WC1(+) gammadelta T cells, and a similar proportion of these two subpopulations were found among the dividing cells in antigen-stimulated cultures as ascertained by carboxyfluorescein succinimidyl ester loading.

Protective killed Ehrlichia ruminantium vaccine elicits IFN-gamma responses by CD4+ and CD8+ T lymphocytes in goats.

|
Flow cytometric analysis of stimulated peripheral blood mononuclear cells (PBMCs) collected after each vaccine inoculation indicated that immune CD4+ and CD8+ T cells contribute to the same extent to the production of IFN-gamma, while WC1+ T cells are less important.
|

|
Blocking experiments also suggest that CD8+ need the help of CD4+ T cells in order to produce IFN-gamma.
|

|
Thus, this work underlines the key role of CD4+ T cells in the production of IFN-gamma by immune goat PBMC.
|

|
Since CD4+ and CD8+ T cells collectively contribute to the production of IFN-gamma in most vaccinated animals, and since these responses are associated with protection, it may be that a recombinant vaccine will need to incorporate E. ruminantium antigens capable of driving both responses.

CD4(+) T cells with a memory phenotype (CD45R0(+)) expressing CD25 and CD26 were the predominant cell type responding to antigens.
|
14 |

|
The majority of WC1(+) CD2(-) and a few WC1(-) CD2(+) gammadelta T cells expressed CD25 at time zero.
|
15 |
15557608
|
By 18 months, however, subsets of gammadelta T cells from both control and infected animals showed an increase in expression of CD25, ACT2, and CD26 in the presence of the antigens.

Immunization of cattle with a Leptospira borgpetersenii serovar hardjo-bovis vaccine results in the development of a recall response by WC1(+) gammadelta T cells and CD4(+) alphabeta T cells characterized by proliferation and interferon-gamma production.

|
Both T cell populations had similar transcript profiles for effector molecules, including IFN-gamma, FasL and granzyme B.
|

|
In contrast, transcripts for costimulatory receptors and ligands were notably different following activation, as WC1(+) T cells expressed no or lower levels of transcripts for CD28 and CD40L, while CD4(+) T cells expressed substantial levels of both.
|

|
These results strengthen the hypothesis that these particular activated WC1(+) and CD4(+) T cells have overlapping effector functions and therefore may differ principally with regard to how they are recruited into immune responses.

Initially thought to be CD4 T-cell-derived, the sources of IL-17 are now known to be varied and belong to both the innate and adaptive arms of the immune system.
|

|
Mechanisms for inducing IL-17 production in lymphoid cells are thought to rely on appropriate antigenic stimulation in the context of TGF-β1, IL-6 and/or IL-1β.
|

|
Using culture protocols adapted from human studies, we have effectively induced both bovine CD4(+) and WC1(+) γδ T-cells to produce IL-17 termed Th17 and γδ17 cells, respectively.
