Insect cells or fractions as adjuvant for antigens
DCFirst Claim
1. In an immunogenic, immunological or vaccine composition comprising at least one epitope of interest or antigen wherein the improvement comprises the composition comprising a first component comprising the epitope of interest or antigen isolated from a source other than insect cells and a second component comprising an adjuvant comprising insect cells or a fraction thereof, wherein the insect cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens.

Abstract
Disclosed and claimed is an adjuvant for immunogenic, immunological, antigenic or vaccine compositions. The adjuvant is composed of insect cells or fractions thereof. Disclosed and claimed are also methods for preparing and using the adjuvant and compositions containing the adjuvant. Advantageously, a recombinant baculovirus containing DNA encoding and expressing an epitope of interest or antigen can be infected into insect cells such as insect cells derived from a Lepidopteran species such as S. frugiperda for expression, and the infected insect cells or a fraction thereof can be used with the expressed epitope of interest or antigen as an inventive antigen or in an inventive immunological, antigen or vaccine composition.

- 1. In an immunogenic, immunological or vaccine composition comprising at least one epitope of interest or antigen wherein the improvement comprises the composition comprising a first component comprising the epitope of interest or antigen isolated from a source other than insect cells and a second component comprising an adjuvant comprising insect cells or a fraction thereof, wherein the insect cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens.

4. An immunogenic, immunological or vaccine composition comprising at least one immunologically active component, wherein said immunologically active component consists of an epitope of interest or antigen and as an immunogenicity-enhancing adjuvant, insect cells or a fraction thereof, wherein the insect cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens.
- 15. An immunological, immunogenic or vaccine composition comprising at least one epitope of interest isolated from a source other than insect cells and a separately added adjuvant, wherein the adjuvant comprises insect cells or a fraction thereof, wherein the cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens.
-
26. A kit for the preparation of an immunogenic, immunological or vaccine composition comprising at least one epitope of interest or antigen and an adjuvant, wherein the adjuvant comprises insect cells or a fraction thereof, wherein the cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens;
- said kit comprising the epitope of interest or antigen in a first container, and the adjuvant in a second container, and optionally instructions for admixing the epitope of interest or antigen and the adjuvant and/or for administration of the composition; and
wherein optionally the containers are in a package. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 65)
- said kit comprising the epitope of interest or antigen in a first container, and the adjuvant in a second container, and optionally instructions for admixing the epitope of interest or antigen and the adjuvant and/or for administration of the composition; and
- 36. A method for enhancing the immunogenicity of an isolated epitope of interest or antigen comprising administering the isolated epitope of interest or isolated antigen with or in conjunction with an adjuvant, wherein the adjuvant comprises insect cells or a fraction thereof, wherein the cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens.
-
59. A method for preparing a composition comprising at least one isolated epitope of interest or antigen and as an immunogenicity-enhancing adjuvant insect cells or a fraction thereof, wherein the insect cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens, said method comprising infecting insect cells with a recombinant insect virus comprising at least one exogenous coding nucleic acid molecule for the epitope of interest or antigen and expressing the epitope of interest or antigen, isolating insect cells, isolating the epitope of interest or antigen, and optionally disrupting and/or fractionating the cells, and optionally inactivating the virus.
-
60. A method for preparing a composition comprising at least one isolated epitope of interest or antigen and as an immunogenicity-enhancing adjuvant insect cells or a fraction thereof, wherein the insect cells are obtainable from an insect species which is not biting and/or from an insect species wherein hypersensitivity to the insect cell antigens is low or absent in human and animal species and/or from an insect species which is non-toxic, non-pyrogenic, non-tumorgenic, contains no known retroviruses or other human or animal viruses, mycoplasma or other pathogens, said method comprising admixing the adjuvant and the at least one epitope of interest or antigen.
