STING1 and neoplasm: To determine if this cellular uptake profile was influenced by STING activation, we concurrently administered nAlb-Cy5 with nAlb-diABZI and found that the addition of nAlb-diABZI primarily impacted the myeloid cell composition of the tumor at 24h, resulting in an increased frequency of neutrophils and MDSCs and a reduction in macrophages (Fig. 2k, inset) while slightly biasing nAlb-Cy5 uptake towards macrophages, dendritic cells, and neutrophils.
