Cytokine Induction Comparison: PPE-Micelles vs. PPE-SCKs in Nanoparticle Systems #2043220 (License: Personal Use)

The chart compares induced cytokine counts from eight nanoparticle formulations-grouped by charge type (anionic, cationic, zwitterionic, neutral) and architecture (micelles vs. single-chain knotted polymers, SCKs). Cationic PPE-micelles induce the strongest immune response (~14.5 cytokines), closely followed by cationic PPE-SCKs (~12.5), while neutral and PEBP-b-PBYP variants show minimal activation (<2). Zwitterionic and anionic forms exhibit intermediate or low activity depending on architecture.

Used in scientific publications, grant proposals, or biotech product documentation to illustrate immunogenicity profiles of poly(phenylene ethynylene)-based nanocarriers; supports decisions in drug delivery system design where controlled immune activation is desired or must be minimized.
