The innate and adaptive responses of the immune system are connected and orchestrated through the action of the dendritic cell, which acts as a conductor, recognizing the telltale patterns of an unfamiliar invader such as the corona virus through its surface receptors, as though reading from a music sheet, and then expressing these patterns in ways that activate and mobilize such immune cells as neutrophils and T cells and B cells, or the cavalry of the immune system. Join Allison in this latest adventure as she explores the intricacies of the immune symphony and how the provision of adjuvant function in the process of vaccination may help prepare and effect the desired immune response.
