Interstitial fluid pressure (IFP) in DMBA-induced rat mammary tumours was measured by micropuncture with sharpened glass capillaries (diameter 1-3 micron) and by the 'wick-in-needle' technique (WIN). IFP in the superficial layers of the tumours (depth less than 800 micron) was measured with micropuncture, while WIN was used for measurements in deeper areas.(More)
A new monoclonal rat anti-human lymphocyte antibody (CAMPATH-1) which lyses cells with autologous human complement was used for depletion of T lymphocytes from human bone-marrow allografts in vitro before transplantation in 11 high-risk patients. HLA-matched siblings were used as marrow donors. T-cell depletion was substantial when measured by E-rosette(More)
Cannabidinoids are components of the Cannabis sativa (marijuana) plant that have been shown capable of suppressing inflammation and various aspects of cell-mediated immunity. Cannabidiol (CBD), a non-psychoactive cannabidinoid has been previously shown by us to suppress cell-mediated autoimmune joint destruction in an animal model of rheumatoid arthritis.(More)
Oral linomide, (quinoline-3-carboxamide), has been shown to prevent autoimmune insulitis, islet destruction, and diabetes in NOD mice treated at an early stage of the disease, but confers only partial protection in animals with advanced disease. Reg protein, the gene product of a complementary DNA isolated from a regenerating rat islet library, has been(More)
CD44 is a multistructural and multifunctional glycoprotein, the diversity of which is generated by alternative splicing. In this communication we review some aspects related to CD44 structure and function in experimental autoimmune inflammation, focusing on research performed in our own laboratory. We have found that CD44 targeting by antibody, passively(More)
Mice carrying the B cell leukemia (BCL1)+ were successfully treated by total lymphoid irradiation (TLI), cyclophosphamide, and allogeneic bone marrow (BM) transplantation. Long-term survivors were examined for residual BCL1 cells and for the ability to transfer adoptively graft vs. leukemia (GVL) activity. Residual BCL1 cells could not be detected in the(More)
We have studied the effect of low-dose heparin on GVHD, marrow engraftment and graft-versus-leukemia (GVL) effects in an experimental murine model. Recipient (C57BL/6 x BALB/c) F1 mice were transplanted with C57BL/6 marrow and/or spleen cells and treated with daily sc injection of 5 micrograms heparin for 30 days. We have shown that heparin in low doses(More)
