    摘要: A recombinant DNA containing a sequence (1) coding for a polypeptide heterologous to a filamentous haemagglutinin of Bordetella (Fha) fused within the reading frame to a sequence (2) located upstream from the first sequence. Sequence (2) codes for at least part of the Fha precursor, which part comprises at least the N-terminal region of a truncated mature Fha protein, which contains the interaction site of Fha and heparin and the secretion domain. This Fha protein is under the control of a promoter recognized by the cell polymerases of B. pertussis and is inserted into a B. pertussis cell culture, is expressed in the culture and excreted into the cell culture medium. The invention uses both the abilities of Bordetella and particularly B. pertussis to secrete or surface expose the heterologous polypeptide fused to the Fha portion corresponding to sequence (2), which does not appear to produce extracellular proteases, and the ease with which filamentous haemagglutinins can be isolated from other Bordetella proteins.

    摘要: New lymphokine and its isolation and purification process. Said lymphokine is comprised of a factor obtained from T cells stimulated by concanavaline A or by an antigen capable of inhibiting the IgE-dependent platelet citotoxicity with respect to young larvae of S. Mansoni, of strongly reducing the chemiluminescence of blood platelets in a reaction IgE-anti-IgE, which is a correlate of the anti-parasite cytotoxicity, and of inhibiting the platelet activation in non-IgE dependent intolerences. Application as suppressor agent for suppressing platelet activation and as immunomodulator medicament of allergies.
