Comparative Analysis of Linear and Angular Measurements on Digital Orthopantomogram with Calcaneus Bone Mineral Density

Background: Bone remodeling is a continuous and complex process which occurs throughout life.Radiomorphometric and radioangular indices on the orthopantomogram are the predictors of bone remodeling associated with mandible.Bone mineral density is the amount of calcified tissue in a certain volume of the bone.Materials and Methods: Fifty normal heal

Targeting CD28, CTLA-4 and PD-L1 costimulation differentially controls immune synapses and function of human regulatory and conventional T-cells.

CD28, CTLA-4 and PD-L1, the three identified ligands for CD80/86, are pivotal positive and negative costimulatory molecules that, among other functions, control T cell motility and formation of immune synapse between T cells and antigen-presenting cells (APCs).What remains incompletely understood is how CD28 leads to the activation of effector T ce
