BACKGROUND AND PURPOSE Enlimomab, a murine monoclonal anti-human intercellular adhesion molecule (ICAM)-1 antibody, had a negative outcome in a multicenter acute-stroke trial. We did a bedside-to-bench study in standardized rat stroke models to explore mechanisms for these untoward results. METHODS After focal brain ischemia in Wistar rats and(More)
BACKGROUND Multiple organ failure after serious injury or illness is a major determinant of mortality. An initial insult is believed to "prime" circulating neutrophils and induce systemic inflammation. Thereafter, a second insult will precipitate distant organ injury. The aim of these studies was to evaluate circulating neutrophil function after mesenteric(More)
Subpopulations of cancer cells with the capacity of generating solid tumors have been characterized. In various cancer types, including prostate cancer cells, a side population (SP) and CD133-expressing cells have been proposed as containing a population cancer cells with stem-like ability. Therefore the aim of this work was to determine, in prostate cancer(More)
B cells lacking individual NF-kappa B/Rel family members exhibit defects in activation programs. We generated small resting B cells lacking p65 or p50 alone, or lacking both p50 and p65, then evaluated the ability of these cells to proliferate, secrete Ig, and undergo Ig class switching. B cells lacking p65 proliferated well in response to all stimuli(More)
4-1BB (CD137) is induced on activated CD4(+) and CD8(+) T cells and delivers a costimulatory signal upon binding the 4-1BB ligand (4-1BBL) expressed on antigen-presenting cells. Induction of 4-1BB is dependent on activation via the T-cell receptor (TCR) and possibly CD28. It was previously demonstrated that both an in vivo protein (pneumococcal surface(More)
Cancer stem-like cells have been identified in both primary tumors and in cell lines and seem to have a high degree of inherent resistance to traditional chemotherapeutic agents. Relapsed cancers including neuroblastoma are generally chemotherapy-resistant and carry a very poor prognosis. We investigated the side populations of three pairs of neuroblastoma(More)
Here we show that distinct subpopulations of cells exist within traumatic human extremity wounds, each having the ability to differentiate into multiple cells types in vitro. A crude cell suspension derived from traumatized muscle was positively sorted for CD29, CD31, CD34, CD56 or CD91. The cell suspension was also simultaneously negatively sorted for(More)
Targeting mutations and amplifications in the EGFR has been successful precision therapy for cancers of the lung, oral cavity and gastrointestinal track. However, a systemic immune reaction manifested by dose-limiting inflammation in the skin and gut has been a consistent adverse effect. To address the possibility that intra-tumoral immune changes(More)
The preparation of polyvalent antisera to ribosomal vaccines from Pseudomonas aeruginosa is described. The ability of these antisera to protect mice by passive immunization against challenge with randomly chosen, clinically isolated strains of P. aeruginosa is reported. Significant protection was achieved against 34 of 40 strains tested (85%). Included(More)
