The aim of this study was to investigate the frequency and possible clinical relevance of SSA/Ro antibodies, as determined by enzyme-linked immunosorbent assay (ELISA), in patient sera not exhibiting a concomitant positive reaction by the standard immunofluorescence (IF) test using HEP-2 cells as substrate. SSA/Ro reactivity, as shown by ELISA, was found in(More)
BACKGROUND The high interstitial fluid pressure (IFP) in solid tumors restricts the access to nutrients, oxygen and drugs. MATERIAL AND METHODS We investigated the ability of the peptide AF-16, involved in water and ion transfer through cell membranes, to lower the IFP in two different solid rat mammary tumors, one chemically induced, slowly growing, and(More)
Porcine fetal islet-like cell clusters (ICC) or isolated rat islets were implanted under the kidney capsule of normoglycemic rats. The animals were sacrificed 1, 3, 6, 12, or 24 days after transplantation, and a detailed morphological and phenotypic characterization of the different cellular subtypes infiltrating the xenograft was performed and compared(More)
Fetal porcine islet-like cell clusters (ICC) were transplanted under the renal capsule of normoglycemic normal or athymic (nu/nu) C57BL/6 mice. Control animals were implanted with allogeneic minced kidney tissue from C57BL/Ks mice. The animals were killed 6 or 14 days after transplantation and the grafts were processed for flow cytometric analyses or(More)
The serum levels of soluble intercellular adhesion molecule 1 (ICAM-1) were significantly elevated (P < .001) in patients with chronic B-lymphocytic leukemia (B-CLL, n = 113) compared with healthy controls (n = 31). sICAM-1 levels in B-CLL were positively correlated to the tumor mass as reflected by the modified Rai and the Binet staging systems, lymphocyte(More)
The process of islet xenograft rejection is still poorly understood. To elucidate further possible mechanism(s) involved in xenograft rejection, the effect of different immunization protocols was investigated. Fetal porcine islet-like cell clusters (ICCs) were transplanted under the kidney capsule in otherwise untreated rats, rats pre-immunized by s.c.(More)
Adoptive T-cell therapy of cancer is a treatment strategy where T cells are isolated, activated, in some cases engineered, and expanded ex vivo before being reinfused to the patient. The most commonly used T-cell expansion methods are either anti-CD3/CD28 antibody beads or the "rapid expansion protocol" (REP), which utilizes OKT-3, interleukin (IL)-2, and(More)
