Protein-Protein interactions - manually collected from original source literature:
Studies that report less than 10 interactions are marked with *
Text-mined interactions from Literome
Satoh et al., Vaccine 2005
(HIV Infections) :
The ability of these
HLA-A*2601 binding peptides to
induce peptide-specific
CD8 ( + ) T cells was tested by stimulating PBMCs from HIV-1 infected individuals having HLA-A*2601 with these peptides
Botten et al., J Virol 2006
(Lassa Fever) :
We identified three peptides ( GPC ( 42-50 ), GLVGLVTFL ; GPC ( 60-68 ), SLYKGVYEL ; and GPC ( 441-449 ), YLISIFLHL ) that displayed high-affinity binding ( < or =98 nM ) to
HLA-A*0201 ,
induced CD8 ( + ) T-cell responses of high functional avidity in HLA-A*0201 transgenic mice, and were naturally processed from native LASV GPC in human HLA-A*0201 positive target cells
Botten et al., J Virol 2007
(Lymphocytic Choriomeningitis) :
We identified four HLA-A*0201 restricted peptides-nucleoprotein NP ( 69-77 ), glycoprotein precursor GPC ( 10-18 ), GPC ( 447-455 ), and zinc binding protein Z ( 49-58 ) -that displayed high-affinity binding ( < or =275 nM ) to
HLA-A*0201 ,
induced CD8 ( + ) T-cell responses of high functional avidity in HLA-A*0201 transgenic mice, and were naturally processed from native LCMV antigens in HLA restricted human antigen presenting cells
Kvistborg et al., Hum Immunol 2008
(Neoplasms) :
Characterization of a single peptide derived from cytochrome P450 1B1 that elicits spontaneous
human leukocyte antigen (HLA)-A1 as well as HLA-B35 restricted
CD8 T-cell
responses in cancer patients
Schenk et al., Am J Transplant 2009
:
Donor-reactive
CD8 memory T-cell infiltration, proliferation and ICOS expression are
regulated by donor
class I MHC molecule expression
Tewalt et al., PLoS Pathog 2009
:
Virus-specific
CD8 ( + ) T cells ( T ( CD8+ ) ) are initially
triggered by
peptide-MHC Class I complexes on the surface of professional antigen presenting cells ( pAPC )
Takada et al., J Exp Med 2009
:
However, distinct from this effect,
class I MHC deprivation also
enhanced naive
CD8 T cell responsiveness to low-affinity ( but not high-affinity ) peptide-MHC ligands
Giannoni et al., Mol Ther 2013
(Melanoma) :
Expression of human
HLA-A*0201 in NSG-A2 recipient mice
led to significantly increased numbers of human
CD8 ( + ) and CD4 ( + ) T cells expressing the F5 TCR, compared with control NSG recipients
Guehler et al., Gastroenterology 1999
:
These results suggest that
CD8 ( + ) TCR gamma delta IELs do not
require class I MHC for development but support the notion that antigens presented by class I MHC molecules are involved in the peripheral expansion and differentiation of this subset
