Abstract
Microbial biochemicals have been indicated as the primary stimulators of innate immunity, the first line of the body's defence against infections. However, the influence of topological features on a microbe's surface on immune responses remains largely unknown. Here we demonstrate the ability of TiO2 microparticles decorated with nanospikes (spiky particles) to activate and amplify the immune response in vitro and in vivo. The nanospikes exert mechanical stress on the cells, which results in potassium efflux and inflammasome activation in macrophages and dendritic cells during phagocytosis. The spiky particles augment antigen-specific humoral and cellular immune responses in the presence of monophosphoryl lipid A and elicit protective immunity against tumour growth and influenza viral infection. The study offers insights into how surface physical cues can tune the activation of innate immunity and provides a basis for engineering particles with increased immunogenicity and adjuvanticity.

immunity, the first line of the body's defence against infections. However, the influence of topological features on a microbe's surface on immune responses remains largely unknown. Here we demonstrate the ability of TiO<sub>2</sub> microparticles decorated with nanospikes (spiky particles) to activate and amplify the immune response in vitro and in vivo. The nanospikes exert mechanical stress on the cells, which results in potassium efflux and inflammasome activation in macrophages and dendritic cells during phagocytosis. The spiky particles augment antigen-specific humoral and cellular immune responses in the presence of monophosphoryl lipid A and elicit protective immunity against tumour growth and influenza viral infection. The study offers insights into how surface physical cues can tune the activation of innate immunity and provides a basis for engineering particles with increased immunogenicity and adjuvanticity.</div></front></TEI><affiliations><list><country><li>République populaire de Chine</li><li>États-Unis</li></country><region><li>Guangdong</li><li>Massachusetts</li></region><settlement><li>Jiangmen</li></settlement></list><tree><country name="République populaire de Chine"><region name="Guangdong"><name sortKey="Wang, Ji" sort="Wang, Ji" uniqKey="Wang J" first="Ji" last="Wang">Ji Wang</name></region><name sortKey="Chen, Hui Jiuan" sort="Chen, Hui Jiuan" uniqKey="Chen H" first="Hui-Jiuan" last="Chen">Hui-Jiuan Chen</name><name sortKey="Hang, Tian" sort="Hang, Tian" uniqKey="Hang T" first="Tian" last="Hang">Tian Hang</name><name sortKey="He, Gen" sort="He, Gen" uniqKey="He G" first="Gen" last="He">Gen He</name><name sortKey="Liu, Fanmao" sort="Liu, Fanmao" uniqKey="Liu F" first="Fanmao" last="Liu">Fanmao Liu</name><name sortKey="Liu, Guishi" sort="Liu, Guishi" uniqKey="Liu G" first="Guishi" last="Liu">Guishi Liu</name><name sortKey="Tao, Jun" sort="Tao, Jun" uniqKey="Tao J" first="Jun" last="Tao">Jun Tao</name><name sortKey="Xiao, Shuai" sort="Xiao, Shuai" uniqKey="Xiao S" first="Shuai" last="Xiao">Shuai Xiao</name><name sortKey="Xie, Xi" sort="Xie, Xi" uniqKey="Xie X" first="Xi" last="Xie">Xi Xie</name><name sortKey="Yang, Bo Ru" sort="Yang, Bo Ru" uniqKey="Yang B" first="Bo-Ru" last="Yang">Bo-Ru Yang</name><name sortKey="Yang, Chengduan" sort="Yang, Chengduan" uniqKey="Yang C" first="Chengduan" last="Yang">Chengduan Yang</name></country><country name="États-Unis"><region name="Massachusetts"><name sortKey="Yu, Yang" sort="Yu, Yang" uniqKey="Yu Y" first="Yang" last="Yu">Yang Yu</name></region><name sortKey="Wu, Mei X" sort="Wu, Mei X" uniqKey="Wu M" first="Mei X" last="Wu">Mei X.
