Immunization with peptide encapsulated within synthetic spores activates T cell responses and reduces tumor growth | mBio
Effective delivery of antigens to the immune system is essential for activating the
adaptive immune system. Synthetic Spore Husk-Encased Lipids (SSHELs) are synthetic bacterial spore-like particles, w...

Immunization with peptides can elicit antigen-specific T cell responses, but they're not widely used because they are poorly immunogenic and are rapidly cleared. Domenico D'Atri solves this by using our "SSHEL" platform (synthetic bacterial spores) .

My reviewing style has changed over time. Rather than litigate every little thing, and pushing my own ideas, I focus only on 2 things:
(1) Are the claims interesting/important?
(2) Does the evidence support the claims?
Most of my reviews these days are short and focused.
