End-organ damage in a mouse model of fulminant liver inflammation requires CD4+ T cell production of IFN-gamma but is independent of Fas.

|
The BALB/c-Tgfb1(-/-) mouse exhibits extensive, spontaneously developing necroinflammation in the liver, accompanied by the accumulation of IFN-gamma-producing CD4(+) and CD8(+) T cells.

|
In Tgfb1(-/-) liver, CD4(+) T cells were more numerous than CD8(+) T cells and NK cells, and produced more IFN-gamma.
|

|
Depletion of CD4(+) T cells eliminated both the elevation in plasma IFN-gamma and aspartate aminotransferase, whereas depletion of CD8(+) T cells did not.
|

|
Rag1(-/-)Tgfb1(-/-) mice exhibited neither IFN-gamma elevation nor tissue damage, indicating that NK cells are not sufficient.

|
IFN-gamma was required for strong overexpression of class II genes but not for CD4(+) T cell activation, oligoclonal expansion, or accumulation in the liver.

|
Finally, whereas Tgfb1(-/-) CD4(+) T cells overexpressed Fas ligand, hepatocellular damage was observed in Fas(lpr/lpr)Tgfb1(-/-) mice, indicating that liver pathology is Fas independent.

|
We conclude that liver damage in this model of fulminant autoimmune hepatitis is driven by CD4(+) T cell production of IFN-gamma, is independent of both CD8(+) T cells and the Fas ligand/Fas pathway, and is not explained by a lack of PD-L1 expression.

TNF-α(+) and IFN-γ(+) CD4(+) T cells expressed significantly higher levels of T-box transcription factors T-bet with graded loss of Eomesodermin (Eomes) expression (T-bet(Hi)Eomes(Hi/Lo)) when compared with TNF-α(+) CD4(+) T cells expressing lower levels of both T-bet and Eomes (T-bet(-)Eomes(-)).

|
Furthermore, TNF-α(+) and IFN-γ(+) CD4(+) T cells expressed significantly higher levels of perforin and interleukin (IL)-2 and displayed a terminally differentiated phenotype (CCR7(-)CD27(-)CD45RA(-)CD57(+)CD62L(-)).

|
In contrast, TNF-α(+) alone CMV-specific CD4(+) T cells were predominantly early-memory phenotype with a proportion of these cells displaying T memory stem-cell phenotype (CD95(+)CD45RA(+)CCR7(+)CD27(+)).

|
In vitro stimulation of CMV-specific CD4(+) T cells with viral antigen in the presence of IL-12 was sufficient to dramatically change the transcriptional and functional profile of TNF-α(+) CD4(+) T cells, whereas TNF-α(+) and IFN-γ(+) CD4(+) T cells remained unaltered.
