• • Membrane Proteomics Exploring Hidden Functions and Interactions in the Cell Membrane

  The cell membrane is a barrier that separates the internal and external environments of the cell. It not only maintains the integrity of the cell structure but also plays crucial roles in many biological processes. In addition to its traditional structure and functions, the cell membrane also harbors numerous hidden functions and interactions that are vital for cellular regulation and communication.

• • How Does Exosome Proteomics Identify Differentially Expressed Exosomal Proteins?

  Extracellular vesicles are a type of small membrane vesicles secreted by cells, containing abundant proteins, nucleic acids, and bioactive molecules. In recent years, the study of proteomics of extracellular vesicles has gained widespread attention.

• • How to Use Label-Free Quantitative Proteomics to Reveal Molecular Mechanisms?

  Proteomics is an important technique in contemporary biomedical field which helps us to gain deeper insights into the complex molecular mechanisms within cells and organisms.
