Text-mined interactions from Literome
Bright et al., J Immunol 1999
(Encephalomyelitis, Autoimmune, Experimental) :
Inhibition of either Jak-2 or
Tyk-2 leads to a decrease in the IL-12 induced tyrosine phosphorylation of Stat3, but not of
Stat4 , protein
Paradowska-Gorycka et al., Scand J Immunol 2010
(Arthritis, Rheumatoid...) :
IL-23 binding to an IL-23 receptor expressed on dendritic cells, macrophages and monocytes triggers the activation of Jak2 and
Tyk2 , which in turn phosphorylates STAT1, STAT3, STAT4 and STAT5 as well as
induce formation of
STAT3-STAT4 heterodimers
Ahn et al., J Immunol 1998
:
While IL-12 is known to activate JAK2 and
TYK2 and
induce the phosphorylation of
STAT4 and STAT3, little is known regarding how the activation of these signaling molecules is related to the biologic effects of IL-12
