摘要:
A transgenic mouse with alterations in a PA28 beta gene is prepared by introduction of an altered PA28 beta gene into a host mouse. The resulting transgenic animals do not produce functional PA28 molecules. Cells and cell lines derived from these animals also contain the altered PA28 beta gene.

Cytotoxic T lymphocytes (CTLs) specific for antigenic peptides derived from IgE molecules can be generated in vitro by stimulating resting naive CD8 T+ cells with IgE peptides presented by artificial antigen presenting cells. The IgE specific CTLs lyse the target cells loaded with IgE peptides in vitro and inhibit antigen specific IgE responses in vivo . In addition, adoptive transfer of the IgE specific CTLs to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific CTLs provide a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocytes (CTLs) in vitro. The CTLs induced by peptides identified from CD40L can kill activated CD4+ T cells. In vitro generated CTLs specific for CD40L inhibit CD4-dependent antibody responses of all isotypes in vivo. In contrast, CTLs induced by antigenic peptides derived from IgE specifically inhibit IgE responses, and adoptive transfer of CD40L-specific CTL to NOD mice at early age delay the development of diabetes in NOD mice. In vitro generated CTLs specific for non-tumor self-antigens expressed on activated CD4+ T cells regulate immune responses in vivo .
摘要:
The present invention provides aqueous pharmaceutical formulations of erythropoietin that are free of human serum blood products, stabilized with a quantity of an amino acid and a sorbitan mono-9-octadecenoate poly(oxy-1,2-ethanediyl) derivative. The present invention also provides aqueous stable, preserved pharmaceutical formulations of erythropoietin that contain an antimicrobial quantity of cresol and a quantity of an amino acid.
摘要:
At the provider edge of a core network, an egress interface may schedule based on a class dominance model, a destination dominance model or a herein-proposed class-destination dominance model. In the latter, queues are organized into sub-divisions, where each of the subdivisions includes a subset of the queues having a per hop behavior in common and at least one of the subsets of the queues is further organized into a group of queues storing protocol data units having a common destination. Scheduling may then be performed on a destination basis first, then a per hop behavior basis. Thus providing user-awareness to a normally user-unaware class dominance scheduling model.
