Digoxin is a drug with a narrow therapeutic index, which is substrate of the ATP-dependent efflux pump P-glycoprotein. Increased or decreased digoxin plasma concentrations occur in humans due to inhibition or induction of this drug transporter in organs with excretory function such as small intestine, liver and kidneys. Whereas particle size, dissolution(More)
Cell lineages, which shape the body architecture and specify cell functions, derive from the integration of a plethora of cell intrinsic and extrinsic signals. These signals trigger a multiplicity of decisions at several levels to modulate the activity of dynamic gene regulatory networks (GRNs), which ensure both general and cell-specific functions within a(More)
Adipose tissue is the largest compartment in the mammalian body for storing energy as fat, providing an important reservoir of fuel for maintaining whole body energy homeostasis. Herein, we identify the transcriptional cofactor hairless (HR) to be required for white adipogenesis. Moreover, forced expression of HR in non-adipogenic precursor cells induces(More)
Clonal immunoglobulin and T-cell receptor gene rearrangements are useful in distinguishing reactive lymphoproliferations from neoplastic processes. Here, we report a case of transient clonal expansion of CD8+ CD57- T-large granular lymphocytes (T-LGL) during primary cytomegalovirus infection. This case underlines that clonal expansion of T-LGL could be a(More)
Tuberculin-skin-test (TST) is widely used for the diagnosis of Tuberculosis. Negative TSTs are occasionally found in individuals vaccinated or infected by Mycobacterium tuberculosis. We show that false negative results are due to a lack of the Tuberculin-specific immune response as replacing tuberculin by unselected M. tuberculosis antigens improved the(More)
Over the last 10 years, 240 cases of hyperplasic lymphadenitis have been systematically tested in our institution for the presence of the human immunodeficiency virus (HIV). This series comprised patients between 15 and 90 years (median of age: 38.51) without a past history of HIV infection. The technical approach consisted in an immunohistochemical(More)
