Figure 1. Cargo diversity across bacterial extracellular vesicle populations. Representative cargo classes include metabolites and enzymes, microbe-associated molecular patterns, sRNAs, and amyloids and proteases. Separate vesicles illustrate population-level diversity and do not imply universal co-packaging. The contribution of vesicular delivery to curli-mediated effects remains unresolved. BEVs: Bacterial extracellular vesicles; GABA: γ-aminobutyric acid; LPS: lipopolysaccharide; OMVs: outer membrane vesicles; PG: peptidoglycan; PSA: polysaccharide A; sRNAs: small noncoding RNAs; tRNA: transfer RNA.
