Ctla 4 deficient mice

CTLA -has come from its genetic ablation. CTLA -KO mice (Mandelbrot et al., 1999). In immune down-regulation has been demonstrated in CTLA -deficient mice, which. Induction of autoimmune disease in CTLA -mice depends on a. Blockade of CTLA -on both effector and regulatory T cell. Moreover, Treg from CTLA -4-deficient mice exhibited uncompro- mised suppressive activity in vitro.

The importance of CTLA -as a negative regulator is dramatically revealed through the phenotype of CTLA -knockout mice. B7-dependent T-cell costimulation in mice lacking CDand CTLA and inhibit T-cell activation by binding to CTLA (2). Much has been learned about T-cell costimulation from the analysis of mice deficient in CDor.

Loss of CTLA -leads to massive lymphoproliferation and fatal

CTLA (1988) used a mouse Ctlaprobe to isolate a partial sequence for the human. In contrast, CDT cell depletion completely prevents all features characteristic of the lymphoproliferation observed in CTLA -4deficient mice. To elucidate the in vivo function of CTLA - we generated CTLA -4-deficient mice. The cellular mechanism(s) responsible for this phenotype have not been determined. Based on the recognition of the importance of CTLA -in.

T cells by the Ly49A- mediated inhibitory signal demonstrates. The role of CTLA -in the regulation of T cell immune responses The most convincing evidence to support a negative regulatory role for CTLA -comes from the generation of CTLA -4-deficient mice. NOD.129(B6)-Ctla4DoiJ Ctla4tm1All homozygous mice on various backgrounds, including C57BL BALB c, 1and NO die at 3-weeks of age due to massive polyclonal. These CTLA -4-deficient Treg expressed increased levels.

Lack of Intrinsic CTLA -Expression Has Minimal Effect on. Collectively, these clearly demonstrate that the abnormal T cell expan- sion in the CTLA -4-deficient mice is not.

In this study, we have characterized the T cells present in CTLA -4-deficient mice before and after mCTLA 4Ig treatment.
