IL-17-secreting CD4(+) T cells are critically involved in inflammatory immune responses. Development of these cells is promoted in vivo and in vitro by IL-23 or TGFbeta1 plus IL-6. Despite growing interest in this inflammatory Th subset, little is known about the transcription factors that are required for their development. We demonstrate that Stat3 is(More)
STAT4 is a critical component in the development of inflammatory adaptive immune responses. It has been extensively characterized as a lineage-determining factor in Th1 development. However, the genetic program activated by STAT4 that results in an inflammatory cell type is not well defined. In this report, we use DNA isolated from STAT4-chromatin(More)
STAT4, a critical regulator of inflammation in vivo, can be expressed as two alternative splice forms, a full-length STAT4alpha, and a STAT4beta isoform lacking a C-terminal transactivation domain. Each isoform is sufficient to program Th1 development through both common and distinct subsets of target genes. However, the ability of these isoforms to mediate(More)
Signal transducer and activator of transcription 6 (STAT6) is critical for IL-4 and IL-13 responses, and necessary for the normal development of Th2 cells. We previously generated mice that express a constitutively active STAT6 (STAT6VT) under control of the CD2 locus control region, which directs expression to the T-cell compartment. We now describe that a(More)
Tissue-resident memory T (TRM) cells persist indefinitely in epithelial barrier tissues and protect the host against pathogens. However, the biological pathways that enable the long-term survival of TRM cells are obscure. Here we show that mouse CD8+ TRM cells generated by viral infection of the skin differentially express high levels of several molecules(More)
Long-standing burns, fissures, and ulcers that undergo malignant transformation into a variety of malignancies, including squamous cell carcinoma, is commonly referred to as a Marjolin's ulcer. It is well recognized that squamous cell carcinomas of the lung and esophagus can cause humoral hypercalcemia of malignancy secondary to paraneoplastic secretion of(More)
