Diminished rosetting capacity of T cells is a well-known phenomenon in Hodgkin’s disease, and inhibitors of E rosette formation have been reported to be present in the plasma of patients with Hodgkin’s disease. The cell line L428, representing an in vitro counterpart of Hodgkin and Sternberg-Reed cells, could be shown to release a factor capable of suppressing the binding of sheep red blood cel...

Introduction Metabolic imaging with hyperpolarised C1-pyruvate [1] requires efficient spectral-spatial sampling schemes in order to acquire as much information from the precious non-recoverable polarisation as possible. One approach is to excite the magnetisation with a small-tip angle and apply efficient readout trajectories during the FID, like for instance EPSI (echo-planar spectroscopic ima...

It is a variant of benign melanocytic naevus composed of spindled and epithelioid melanocytes, found predominantly in children and adolescents. A number of histopathological variants have been reported, such as desmopl...

We describe a new monoclonal murine antibody that reacts with a 50,000-mol wt polypeptide that appears to be present on all E-rosetting cells. We conclude that this antigen is either identical to or closely associated with the E receptor because of (a) the high degree of concordance between E-rosette formation and 9.6 antigen expression, (b) the inhibition of rosette formation by preincubation ...

The self-assembly of a DNA-analogue hexameric rosette from triaminopyrimidine and cyanuric acid-based nucleosides, and its subsequent aggregation into rod-like morphologies is reported.

Splenopentin (SP-5), is a pentapeptide corresponding to the amino acid sequence 32-36 (Arg-Lys-Glu-Val-Tyr) of the splenic hormone splenin. Its synthetic analogs: Lys-Lys-Glu-Val-Tyr(1) and D-Lys-Lys-Glu-Val-Tyr (2) have been evaluated for active T-cell rosette (CD2R), total T-cell rosette (CD2), interleukin-2 (IL-2) stimulation and effect on antibody production. SP-5 as well as both the analog...

Using a radioimmunoassay, increased levels of a human thymus/leukemia-associated antigen (HThy-L) have been detected in leukemic cells and plasma from most patients with E-rosette-positive acute lymphoblastic leukemia (ALL) and a number of patients with E-rosette-negative ALL, acute myeloblastic leukemia (AML), acute monomyelocytic leukemia (AMML), and acute undifferentiated leukemia (AVL). Low...
