Enhancement of graft-versus-host reaction and delayed cutaneous hypersensitivity in mice by ubenimex.
نویسندگان
چکیده
The effect of ubenimex on graft-versus-host reaction and delayed cutaneous hypersensitivity in mice was studied. Ubenimex enhanced the graft-versus-host reaction in a dose range from 0.005 to 0.5 mg/kg. Ubenimex inhibited the aging-caused decrease of delayed cutaneous hypersensitivity to oxazolone and the efficacy was greater with older mice. Ubenimex also inhibited mitomycin C and L1210-caused decreases of delayed cutaneous hypersensitivity to picryl chloride. However, the excess decrease caused by mitomycin C was not significantly altered by ubenimex.

Experimental studies of immunologically mediated enteropathy. Development of cell mediated immunity and intestinal pathology during a graft-versus-host reaction in irradiated mice.
The intestinal component of a graft-versus-host reaction (GvHR) provides a useful experimental model to elucidate the pathogenesis of clinical enteropathies which cause villus atrophy and crypt hyperplasia and which are associated with a local immune response. One to three days after induction of GvHR in heavily irradiated (CBAxBALB/c)F1 mice, a proliferative form of enteropathy developed. Comp...
متن کاملTreatment of chronic cutaneous graft versus host disease (GVHD) with photochemotherapy with Psoralen (PUVA): A report of five cases
Chronic graft versus host disease (GVHD) remains the most common late complication of allogenic stem cell transplantation and the most frequent cause of morbidity and mortality in these patients. To control this condition, immunosuppressive drugs are usually administered at a high dose and for a long time, which may result in several side effects. 5 patients with clinically and histopathologica...
متن کاملLow Dose Psoralen Plus Ultraviolet A (PUVA) Is an Effective and Safe Method for the Treatment of Chronic Graft Versus Host Disease
Background: Chronic graft versus host disease (ch.GVHD) is the most frequent late complication after allogenic stem-cell transplantation. Systemic immunosuppressive agents are usually required to control the disease. Psoralen plus UVA (PUVA) has been used for the treatment of ch.GVHD with variable beneficial effects. The objective of this study was to assess the efficacy and safety of a r...
متن کاملEvaluation of narrow band UVB therapeutic effect on chronic mucocutaneous graft versus host disease lesions: A case series
Background: Chronic graft versus host disease (cGVHD) is a major cutaneous complication of bone marrow transplantation (BMT). Although milder forms of this process may be associated with a lower incidence of tumor recurrences, it is mandatory to develop a more efficient and less harmful therapeutic approach.Methods: This case-series study enrolled 7 patients diagnosed with chronic mucocutaneous...
متن کاملResistance to cutaneous graft-vs.-host disease is not induced in T cell receptor delta gene-mutant mice
The function of murine dendritic epidermal cells (dEC) remains largely speculative, probably because of the lack of a suitable in vivo model, although previous studies suggest that gamma/delta+ dEC may have originally evolved to serve as a self-protection mechanism(s). Our previous study demonstrated that the epidermis of mice that had spontaneously recovered from cutaneous graft-vs-host diseas...
