Biomaterial-based vaccines elicit robust antibodies

Najibi, A.J., et alAdvanced Functional Materials 2022.

Several forms of biomaterial scaffold-based vaccines led to strong and durable antibody titers against a variety of antigen targets (contraception, cancer, infectious disease).

Cryogel vaccines are effective regardless of location

Najibi, A.J., Shih, T-Y, Mooney, D.J. Biomaterials 2022.

Cryogel-based cancer vaccines generate effective T cell and antibody responses independent of injection location, relative to the draining lymph node or tumor.

Chemo-immunotherapy in situ

Wang, H.*, Najibi, A.J.*, et al. Nature Communications 2020.

We used a hydrogel to both deliver chemotherapy, generating cancer antigen in situ, and concentrate activated dendritic cells to mobilize antitumor immunity, forming an effective "antigen-free" vaccine.

Recruited T cells rescue ischemic tissue.

Kwee, B.J., Seo, BR., Najibi, A.J., et al. Science Advances 2019.

A biomaterial scaffold implanted into an ischemic limb recruited antigen-specific Th2-type CD4+ T cells generated by a prior vaccine, supporting angiogenesis and muscle regeneration.

CD4 T cells can boost muscle regeneration.

Kwee, B.J., Budina, E., Najibi, A.J., et al. Biomaterials 2018.

Factors secreted from Th2 and Th17 CD4+ T cells, but not Th1 T cells, supported angiogenesis and myogenesis and may be harnessed to treat ischemic disease.
