摘要:
An objective of the present invention is to facilitate the acquisition of antibody-producing cells that are infiltrating virus-infected cells, cancer cells, abnormal cells forming a benign hyperplasia, and the like, and to improve the efficiency of the production of antibodies as well as nucleic acids encoding them from the antibody-producing cells.The present inventors discovered that, when cancer tissues comprising infiltrating lymphocytes are transplanted into highly immunodeficient animals that do not have T cells, B cells, and NK cells and further exhibit a low IFN production ability, the differentiation and proliferation of infiltrating lymphocytes are unexpectedly promoted, and the number of plasma cells that produce antibodies recognizing cancer tissues increases dramatically, plasma cells can be separated easily, and antibodies or nucleic acids encoding them can be easily prepared from the plasma cells.

Anti-human Mpl antibodies were isolated and purified, and then anti-human Mpl diabodies and anti-human Mpl sc(Fv)2 were purified using genetic engineering techniques. Furthermore, the present inventors succeeded in humanizing anti-human Mpl sc(Fv)2. The diabodies and sc(Fv)2 were assayed for TPO-like agonistic activity, and were found to have activities higher than those of anti-human Mpl antibodies, or activities equivalent to or higher than those of naturally-occurring human TPO ligand.

The present invention aims to provide a novel gene having a reverse transcriptase motif. The invention isolates a novel gene having a reverse transcriptase motif, and gives its complete base sequence determined. The invention also provides a protein encoded by the gene, and an antibody against the protein. The use of them is useful in developing a method for detecting telomerase activity, a method for detecting a cancer cell, a telomerase activity inhibitor, and a method for screening a telomerase activity inhibitor.

Monoclonal antibodies immunospecific for the neutrophil chemotactic factor, IL-8, have been humanized by reshaping the variable regions to conform more closely to human counterparts. These antibodies are useful in immunoassays to detect IL-8 and as ligands on immunoaffinity columns for purification of human IL-8. In addition, the humanized antibodies have an antiinflammatory effect in patients.
摘要:
The present invention discloses a reshaped human antibody against human IL-8 comprising:(A) L chains each comprising:(1) a human L chain C region; and,(2) an L chain V region comprising a human Lchain FR, and an L chain CDR of mouse monoclonal antibody against human IL-8; and,(B) H chains each comprising:(1) a human H chain C region; and,(2) an H chain V region comprising a human Hchain FR, and an H chain CDR of mouse monoclonal antibody against human IL-8. Since the majority of this reshaped human antibody originates in human antibody and the CDR has low antigenicity, the reshaped human antibody of the present invention has low antigenicity to humans, and can therefore be expected to be useful in medical treatment. The present invention further discloses polynucleotides which encode reshaped antibodies against IL-8, as well as host cells and methods to produce these antibodies.
摘要:
A reshaped human antibody to the human IL-6R, comprising: (A) an L chain comprising, (1) a human L chain C region, and (2) an L chain V region comprising human L chain framework regions (FRs), and mouse L chain complementary determination regions (CDRs) of a monoclonal antibody to the IL-6 receptor (IL-6R); and (B) an H chain comprising, (1) a human H chain C region, and (2) an H chain V region comprising human H chain FRs, and mouse H chain CDRs of a monoclonal antibody to the IL-6R. Since major portion of the reshaped human antibody is derived from a human antibody and the mouse CDRs which are less immunogenic, the present reshaped human antibody is less immunogenic to human, and therefor is promised for therapeutic uses.

摘要:
A document processing method and system are provided in which data is inscribed as handwritten information on a blank form in a document form hitherto used or a blank form for a document produced by a word processor or the like. The blank form with the handwritten information data is facsimile-input and is transmitted to a computer which in turn receives the data directly and recognizes the received data to process the document. Initially, the contents or format of a blank form are read to obtain and store information regarding ruled lines and handwritten character input areas. Upon execution of document processing, an input document image received via facsimile is searched for reference ruled lines on the basis of the ruled line information initially stored to positionally adjust the document image and ruled line images in handwritten character input areas are erased from the adjusted document image on the basis of the handwritten character input area information initially stored to recognized handwritten characters. A function of returning the result of recognition or the result of processing by the computer to a sender facsimile or a function of eliminating improper facsimile transmission may be provided by receiving a sender facsimile number as data upon reception of the facsimile document image and storing it or comparing the received number with transmission-allowed facsimile numbers previously registered.
摘要:
Method and system for dispensing a document form including input/output fields into which a character train or a numerical value data train is written on a screen such that the operator can easily correct it on the screen or by a format such that data can be easily input/output into/from the input/output fields thereof for processing. describing a format of the document is read out of a recording medium in which the document format has been written, the read data is displayed on the screen with a format which is the same as or similar to the format written on the recording medium. When the document form is displayed on the screen a character size per character displayed is decided from the read data, the cell is arranged on the basis of the decided character size, extra-cell data such as character or numerical value data or the like is arranged on the basis of the arranged cell, the cell and the extra-cell data are compressed so as not to overflow the display screen, and a processing procedure of items of the format displayed in the display screen is determined.
