Frictional trans-epithelial tissue disruption and collection apparatus and method of inducing or augmenting an immune response
The invention relates to trans-epithelial frictionally abrasive tissue sampling devices for performing biopsies and methods of inducing an immune response against a pathogen, wherein epithelial cells containing the pathogen are disrupted with the frictionally abrasive tissue sampling device to introduce the pathogen into the bloodstream of a patient.
1. A method of inducing or augmenting a papillomavirus immune response comprising:
frictionally disrupting cervical epithelial cells containing a papillomavirus in a region with an apparatus for obtaining a histological sample comprising:
a stiff handle;
a platform at a distal end of the stiff handle; and
a fabric attached to the platform for obtaining a histological sample including:
a backing material securely attached to the platform; and
a plurality of fenestrated loops of a length attached to the backing material, where the plurality of fenestrated loops have a hook end, where a distance from the top of the plurality of fenestrated loops to the bottom of the hook end is less than approximately 20% of the length of the plurality of fenestrated loops, where the stiff handle does not permit the apparatus to bend or bow when pressure is transmitted from the handle to the device head; and
thereby eliciting a papillomavirus immune response in the region.
2. The method of claim 1 , where the disruption of epithelial cells results in one or both the papillomavirus and its molecular components being released to the surrounding tissues and introduced into the bloodstream of a patient.
3. The method of claim 1 , where the papillomavirus is human papillomavirus.
4. The method of claim 1 , where the papillomavirus contains a DNA fragment.
5. The method of claim 1 , where the papillomavirus contains a virally altered DNA.
6. The method of claim 1 , where the papillomavirus contains a protein.
7. The method of claim 6 , where the papillomavirus contains an oncogenic protein.
8. The method of claim 7 , where the papillomavirus contains a cellular oncogenic protein.
9. The method of claim 1 , where the papillomavirus contains an antigenic material.
10. The method of claim 9 , where the antigenic material generates a humoral response.
11. The method of claim 9 , where the antigenic material generates an antibody response.
12. The method of claim 9 , where the antigenic material generates a cell mediated response.
13. The method of claim 9 , where the antigenic material generates one or more of a dendritic cell (DCs), natural killer (NK) cell, macrophage and T lymphocyte response.
14. A method of inducing a papillomavirus immune response against a HPV pathogen that normally evades the immune system comprising:
disrupting cervical epithelial tissue containing the papillomavirus in a region with an apparatus for obtaining a histological sample comprising:
a stiff handle;
a platform at a distal end of the stiff handle; and
a fabric attached to the platform for obtaining a histological sample including:
a backing material securely attached to the platform; and
a plurality of fenestrated loops of a length attached to the backing material, where the plurality of fenestrated loops have a hook end, where a distance from the top of the plurality of fenestrated loops to the bottom of the hook end is less than approximately 20% of the length of the plurality of fenestrated loops, where the stiff handle does not permit the apparatus to bend or bow when pressure is transmitted from the handle to the device head; and
thereby eliciting a papillomavirus immune response in the region.
15. The method of claim 14 , where the disruption of cervical epithelial tissue results in the papillomavirus being introduced into the bloodstream of a patient.
16. A method of inducing a papillomavirus immune response comprising: disrupting cervical epithelial tissue cells containing a papillomavirus in a region with an apparatus for obtaining a histological sample comprising:
a stiff handle;
a platform at a distal end of the stiff handle; and
a fabric attached to the platform for obtaining a histological sample including:
a backing material securely attached to the platform; and
a plurality of fenestrated loops of a length attached to the platform, where the plurality of fenestrated loops have a hook end, where a distance from the top of the plurality of fenestrated loops to the bottom of the hook end is less than approximately 20% of the length of the plurality of fenestrated loops, where the stiff handle does not permit the apparatus to bend or bow when pressure is transmitted from the handle to the device head; and
thereby eliciting a papillomavirus immune response in the region.
17. The method of claim 16 , where the disruption of cervical epithelial tissue cells results in the papillomavirus being introduced into the bloodstream of a patient.
18. The method of claim 16 , where the papillomavirus is a human papillomavirus.
