  • immunodeficiency (pathology)
    Defect in immunity that impairs the body’s ability to resist infection. The immune system may fail to function for many reasons.

    Immunity is the ability of an individual to recognize the “self” molecules that make up one’s own body and to distinguish them from such “nonself” molecules as those found in infectious microorganisms and toxins. This process has a prominent genetic component. Knowledge of the genetic and molecular basis of the mammalian immune system has increased in parallel wi...

IHC uses......

  • immunophilin (protein)
    Rapamycin exerts its immunosuppressive effects by inhibiting the activation and proliferation of T cells. It acts specifically on FK-binding protein 12 (FKBP12), a substance commonly referred to as an immunophilin because it binds to immunosuppressive drugs.

    In disasters such as floods and some hurricanes there is a distinctly long period of impact, which can be separated from a subsequent period of stocktaking or immobility. In earthquakes and explosions, on the other hand, the impact is so brief that the periods can hardly be separated. The combined period of impact and stocktaking is marked initially by a fragmentation of human relations, as......
