This helps the immune system identify the pathogen or foreign invader. A healthy immune system is essential for our survival, as we are constantly exposed to… Read more »

Cytokines: Function, Structure, and Properties

Cytokines refer to a large group of cell-signaling molecules that essentially consists of proteins, peptides, and glycoproteins. They either have short or long chain structures. They are primarily released by immune system cells in order to initiate cell-to-cell interaction in order to generate an immune response. For instance, when white blood cells come in contact with pathogens they immediately release… Read more »
