Furthermore, many PrAMPs are cationic, which aids in their initial interaction with the negatively charged bacterial cell surface. Studies have investigated the potential of mammalian proline-rich peptide compounds as well, expanding the scope of their application.

Beyond their antimicrobial roles, proline-rich peptides have demonstrated a wide range of other health benefits.作者：A Di Stasi·2025·被引用次数：3—Proline-rich antimicrobial peptides (PrAMPs) primarily exert their antimicrobial effects intracellularly, inhibiting protein synthesis. Research has indicated potential applications in areas such as antihypertensive, anti-inflammatory, and antidiabetic therapies, as well as contributing to bone health. The intrinsic disorder of proline-rich proteins (PRPs), which are characterized by repeats of short proline-rich sequences, may also play a role in their diverse functionalities.

The study of proline-rich peptides extends to their chemical and structural diversity. They are described as a chemically and structurally diverse family, with some being cell-penetrating vectors characterized by the presence of pyrrolidine rings. The development of novel proline-rich antimicrobial peptides is an ongoing area of research, with efforts focused on enhancing their activity and combating multi-drug resistant pathogens. For instance, researchers are designing new chimeric proline-rich antimicrobial peptides and investigating methods to enhance their action, such as through dimerization.
