Recently, we reported that IL-21 induces granzyme B (GzmB) and GzmB-dependent apoptosis in malignant CD5(+) B cells from patients with chronic lymphocytic leukemia. Several autoimmune diseases (AD) are associated with enhanced frequencies of CD5(+) B cells. Since AD are also associated with elevated IL-21 and GzmB levels, we postulated a link between CD5(+)(More)
Human B cells are currently not known to produce the proapoptotic protease granzyme B (GrB) in physiological settings. We have discovered that BCR stimulation with either viral Ags or activating Abs in the context of the acute phase cytokine IL-21 can induce the secretion of substantial amounts of GrB by human B cells. Importantly, GrB response to viral Ags(More)
CpG oligodeoxynucleotides (CpG) and IL-21 are two promising agents for the treatment of B-cell chronic lymphocytic leukemia (B-CLL). Recently, we reported that the combination of CpG and IL-21 (CpG/IL-21) can induce granzyme B (GrB)-dependent apoptosis in B-CLL cells. Here, we demonstrate that treatment of B-CLL cells with CpG and IL-21 results in the(More)

The aim of this paper is to point out by means of examples how a disturbance of learning and ability governs the social processes in the environment of a schoolchild, as the reactions influence and finally deform self-confidence and from this, oppressive social situation processes arise which can finally end in "drop-outmanship". This "drop-outmanship" is(More)
