Modulation of STAT signaling by STAT-interacting proteins

The Jak-Stat Signaling Pathway of Interferons System: Snapshots

Interferons (IFNs) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. Although IFNs have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. IFNs exert their pleiotropic effects through their multisubunit cell surface recept...

STAT Proteins and Cancer.

Normal signal transduction is characterized by the regulated biochemical transmission of extracellular stimuli from cell surface receptors to genes in the nucleus. Transmission of the signal proceeds via the specific and sequential activation of a series of second messengers or intermediaries. Ultimately, this sequence of events leads to the induction of unique genetic programs that dictate the...

SnapShot: JAK-STAT Signaling

STAT signaling in inflammation

Since their discovery, STAT proteins have been intimately tied to controlling the development of hematopoietic cells that regulate inflammation, and mediating the responses of target cells to inflammatory cytokines. Although our understanding of STAT protein-dependent gene expression during inflammation has grown considerably over the past 15 years, the identification of new cell types that req...

Interleukin 2 signaling involves the phosphorylation of Stat proteins.

One of the most important cytokines involved in immune response regulation is interleukin 2 (IL-2), a potent activator of the proliferation and function of T lymphocytes and natural killer cells. The mechanisms by which the effects of IL-2 are propagated within cells are not understood. While the binding of IL-2 to its receptor was recently shown to lead to the activation of two kinases, Jak-1 ...
