DCs, which have been called ‘Nature's adjuvants,' express pathogen recognition receptors, such as the Toll‐like receptors (TLRs) and C‐type lectins, which enable them to sense and respond to microbes or vaccines. Dendritic cells are derived from hematopoietic bone marrow progenitor cells (HSC). These progenitor cells initially transform into immature dendritic cells. These cells are characterized by high endocytic activity and low T-cell activation potential. Immature dendritic cells constantly sample the surrounding environment for pathogens such as viruses and bacteria. This is done through p… shell v-power smartdeal
