Title: Inhibition of secretion from non-neuronal cells
Inventor: FOSTER KEITH ALAN
IPC: C12N9/52
Filed: 2000-09-25
Granted: 2013-04-09
Abstract: A method of treatment of disease by inhibition of cellular secretory processes is provided. The method has particular application in the treatment of diseases dependent upon the exocytotic activity of endocrine cells, exocrine cells, inflammatory cells, cells of the immune system, cells of the cardiovascular system, and bone cells. Agents and compositions therefor, as well as methods for manufacturing these agents and compositions, are provided. In a preferred embodiment a clostridial neurotoxin, substantially devoid of holotoxin binding affinity for neuronal cells of the presynaptic muscular junction, is associated with a targeting moiety. The targeting moiety is selected such that the clostridial toxin conjugate so formed may be directed to a non-neuronal target cell to which the conjugate may bind. Following binding, a neurotoxin component of the conjugate, which is capable of inhibition of cellular secretion, passes into the cytosol of the target cell by cellular internalisation mechanisms. Thereafter, inhibition of secretion from the target cell is effected.

Abstract: A computer (30(1)) detects congestion (50, 80) on a network transport medium (32) and in response thereto refrains from sending any packets containing messages. These to be transmitted messages are instead stored (56, 84) by the computer in memory (40). In one embodiment, each message addressed to the same destination addressee computer is stored (84) in a common buffer (38), with a different buffer being allocated to each identified destination addressee computer (30(2) and 30(3)) for the to be transmitted messages. In another embodiment, each such message is encapsulated (54) into a single packet (36) that is stored (56) in the reserved portion. When the congestion condition on the transport medium subsides (58, 86), the one or more messages stored within a given buffer are retrieved from memory and encapsulated (104) within a single packet (36) addressed to the destination addressee computer associated with that given buffer. Alternatively, the stored single packet is retrieved from memory. That single packet is then sent (76, 106) over the transport medium to the identified destination addressee computer.

Abstract: The invention provides antibodies for a mutant form of the epidermal growth factor receptor known as EGFRvIII. This mutant is found only or primarily on the surface of glioblastoma cells, and on cells of breast, ovarian and non-small cell lung carcinomas. The antibodies provided by the invention have higher affinity for EGFRvIII, and form immunotoxins with higher cytotoxicity and yield, than prior art antibodies, including the scFv designated MR1. In particular, the invention provides an antibody, designated MR1-1, which mutates MR1 in the CDR3 of the VH and VL chains to provide an antibody with especially good cytotoxicity. The invention provides additional antibodies in which MR1 is mutated in the CDR1 and 2 of VH or VL, or both, with better binding to EGFRvIII than that of the parental MR1 antibody.
