One of the most common outcomes of pulp inflammation is periapical granuloma formation. Existence of immune cells in these lesions showed involvement of both humoral and cellular immunity in the site. The presence of different antigens in the root canal causes production o various antibodies and consequent immunological reactions. Different theories have been proposed on periapical cysts. The m...

Cell-mediated immunity in rheumatoid arthritis (RA) was assessed by skin testing with six antigens in 107 patients, 94 of whom were age, sex, and race-matched with healthy individuals or patients with diseases unrelated to immunological abnormalities. 20% of RA patients were anergic. Impaired cell-mediated immunity in the RA patients was manifested by a decrease in the magnitude of skin reactiv...
The accumulation of cross-immunity in the host population is an important factor driving the antigenic evolution of viruses such as influenza A. Mathematical models have shown that the strength of temporary non-specific cross-immunity and the basic reproductive number are both key determinants for evolutionary branching of the antigenic phenotype. Here we develop deterministic and stochastic ve...
This panorama of the immune factors in corneal graft rejection covers a spectrum of mechanisms which play a role in the opacification of corneal grafts. Great emphasis has been accorded to the role of transplantation immunity. The clinical and experimental evidence implicating transplantation immunity in the rejection of corneal grafts has been critically reviewed. In addition, evidence is pres...
Europe (8), resident populations in these countries have been exposed to these virus lineages more frequently than populations in Asia, and therefore may have acquired a greater degree of preexisting cross-reactive immunity to pandemic (H1N1) 2009 virus. A recent review of human swine infl uenza infections suggests that they may not be uncommon (9), although the true incidence of human infectio...
