immunohistochemistry for GATA3 on an independent series of cases, Wang et al also showed that GATA3 expression, evidenced in almost half of the cases, identifies a high-risk subset of PTCL, NOS. Although the findings in these 2 independent cohorts are convergent, it will be useful to confirm the clinical correlation of the GATA3 vs TBX21 profiles in another series of PTCL, NOS patients, if poss...
Immunological memory, which protects organisms from re-infection, is a hallmark of the mammalian adaptive immune system and the underlying principle of vaccination. In early life, however, mice and other mammals are deficient at generating memory CD8+ T cells, which protect organisms from intracellular pathogens. The molecular basis that differentiates adult and neonatal CD8+ T cells is unknown...
Cytokines are critical determinants for specification of lineage-defining transcription factors of CD4+ T cell subsets. Little is known, however, about how cytokines regulate expression of T-bet and eomesodermin (Eomes) in effector and memory CD8+ T cells. We now report that IL-12, a signature of cell-mediated immunity, represses Eomes while positively regulating T-bet in effector CD8+ T cells ...
Summary We characterised patients with mantle cell lymphoma (MCL) poor prognosis based on differences in immune infiltration. Different expressions of the tumour markers Cyclin D1 and sex‐determining region Y‐box transcription factor 11 (SOX11), cluster differentiation 3 (CD3), CD4, CD8, CD25, forkhead box protein P3 (FoxP3), T‐box TBX21 (T‐bet), programmed death 1 (PD‐1), programmed‐death liga...
T-bet plays an important role in immunoregulation; it induces the differentiation of Th1 together with the homeobox transcription factor gene Hlx. Recent studies show that T-bet and Th1-associated factors are critical in regulating tumor development. However, the contributions of Hlx in the occurrence and development of cancer remain unknown. In this study, the Hlx, T-bet, Runx3, and IFN-γ were...
GATA-3 and T-box expressed in T cells (T-bet) play central roles in Th-cell development and function. Consistently, studies in mice document their selective expression in Th1 and Th2 cells, respectively. In contrast, it is not clear whether these genes are regulated in human Th cells. Here we show that T-bet expression is polarized to a comparable degree in human and mouse Th-cell cultures, whi...
In rat models, CD4(+)CD25(+) T regulatory cells (Treg) play a key role in the induction and maintenance of antigen-specific transplant tolerance, especially in DA rats with PVG cardiac allografts (1, 2). We have previously described generation of alloantigen-specific Treg (Ts1), by culture of naïve natural CD4(+)CD25(+) Treg (nTreg) with specific alloantigen and IL-2 for 4 days. These cells exp...
Effective immune responses depend upon appropriate T cell differentiation in accord with the nature of an infectious agent, and the contingency of differentiation depends minimally on TCR, coreceptor, and cytokine signals. In this reverse genetic study, we show that the MAPK Erk2 is not essential for T cell proliferation in the presence of optimum costimulation. Instead, it has opposite effects...
PROBLEM How maternal allergy affects the systemic and local immunological environment during pregnancy and the immune development of the offspring is unclear. METHOD OF STUDY Expression of 40 genes was quantified by PCR arrays in placenta, peripheral blood mononuclear cells (PBMC), and cord blood mononuclear cells (CBMC) from 7 allergic and 12 non-allergic women and their offspring. RESULTS...
