AKT3 — CD28
Text-mined interactions from Literome
Jones et al., J Exp Med 2002
:
CD28 dependent
activation of protein kinase
B/Akt blocks Fas mediated apoptosis by preventing death inducing signaling complex assembly
Li et al., J Immunol 2005
:
We also analyze
Akt and glycogen synthase kinase-3beta phosphorylation in
response to stimulation of
CD28 alone
Li et al., Blood 2005
:
T-cell receptor
(TCR)-CD3/CD28 mediated activation of Rap1 and
Akt was retained in Tregs, but activation of Ras, mitogenactivated protein kinase 1/2 ( MEK1/2 ), and extracellular signal regulated kinase 1/2 ( Erk1/2 ) was impaired
Parry et al., Mol Cell Biol 2005
:
Ligation of both CTLA-4 and PD-1 blocked
CD3/CD28 mediated upregulation of glucose metabolism and
Akt activity, but each accomplished this regulation using separate mechanisms ... In contrast, PD-1 signaling
inhibits Akt phosphorylation by preventing
CD28 mediated activation of phosphatidylinositol 3-kinase (PI3K)
Perchonock et al., Mol Cell Biol 2006
(Splenomegaly) :
While
TCR/CD28 mediated activations of phosphotyrosine induction, extracellular signal regulated kinase 1/2, Jun N-terminal protein kinase, IkappaB kinase alpha/beta, and
Akt were unaltered, constitutive activation of p38 mitogen activated protein kinase and its upstream regulators MKK3/6 were observed for ALX-deficient splenocytes
Charvet et al., J Immunol 2006
:
This defect was associated with impaired
TCR/CD28 induced phosphorylation of
Akt and the Forkhead family transcription factor, FOXO1
Pei et al., J Immunol 2008
:
In vivo and in vitro data support a model in which
CD28 costimulation
activates AKT to phosphorylate NF90 at Ser647 and phosphorylation triggers NF90 to relocate to the cytoplasm and stabilize IL-2 mRNA
Dodson et al., Mol Cell Biol 2009
(Encephalomyelitis, Autoimmune, Experimental...) :
Mutation of the proximal tyrosine motif interrupted PI3-kinase binding and prevented
CD28 dependent phosphorylation of protein kinase B
(PKB)/Akt ; however, there was no detectable effect on interleukin-2 (IL-2) secretion, expression of Bcl-X ( L ), or on T-cell function in vivo
Ordoñez-Rueda et al., Eur J Immunol 2009
:
Interestingly, in
response to CD3 plus
CD28 costimulation, CD5 ( -/- ) naïve T cells but not CD5 ( -/- ) nTreg showed lower levels of
p-Akt
Zhu et al., J Immunol 2010
:
Our previous work showed that
CD28 costimulation of T cells
activated AKT to phosphorylate NF90 at Ser ( 647 ) and caused NF90 to undergo nuclear export and stabilize IL-2 mRNA
