abstract = {TYK2 is a member of the JAK family of tyrosine kinases that
is involved in chromosomal translocation-induced fusion
proteins found in anaplastic large cell lymphomas (ALCL)
that lack rearrangements activating the anaplastic lymphoma
kinase (ALK). Here we demonstrate that TYK2 is highly
expressed in all cases of human ALCL, and that in a mouse
model of NPM-ALK-induced lymphoma, genetic disruption of
Tyk2 delays the onset of tumors and prolongs survival of the
mice. Lymphomas in this model lacking Tyk2 have reduced
STAT1 and STAT3 phosphorylation and reduced expression of
Mcl1, a pro-survival member of the BCL2 family. These
findings in mice are mirrored in human ALCL cell lines, in
which TYK2 is activated by autocrine production of IL-10 and
IL-22 and by interaction with specific receptors expressed
by the cells. Activated TYK2 leads to STAT1 and STAT3
phosphorylation, activated expression of MCL1 and aberrant
ALCL cell survival. Moreover, TYK2 inhibitors are able to
induce apoptosis in ALCL cells, regardless of the presence
or absence of an ALK-fusion. Thus, TYK2 is a dependency that
is required for ALCL cell survival through activation of
MCL1 expression. TYK2 represents an attractive drug target
due to its essential enzymatic domain, and TYK2-specific
inhibitors show promise as novel targeted inhibitors for
ALCL.},
