Abstract: An in-vitro process for the quick determination of the infection status of a Mycobacterium tuberculosis infection from whole blood in terms of active or latent tuberculosis, comprising the steps of: stimulating an antigen-specific T cell that is present in a first sample of whole blood with purified protein derivative (PPD) in the presence of antibodies against CD28, or CD28 and CD49d; processing of PPD by antigen-presenting cells (APC) by incubating for 1.5 h to 2.5 h, especially for 2 h, at 35° C. to 39° C., especially at 37° C., optionally with adding CO2; then adding a secretion inhibitor; effecting an intensive mixing; and another incubation for a period of at least 2.5 h at a temperature of from 35° C. to 39° C.

Abstract: The present invention relates to the use of low-dosage erythropoietin for stimulation of physiological mobilization, proliferation and differentiation of endothelial progenitor cells, for stimulation of vasculogenesis, for therapy of diseases related to a dysfunction of endothelial progenitor cells, and for production of pharmaceutical compositions for treatment of such diseases as well as pharmaceutical compositions that include erythropoietin and other suitable active ingredients for stimulation of endothelial progenitor cells.
