Multi-IHC further confirmed that, CD204+ M2 macrophages were more abundant in control tumor (KPC;Ulk1fl/+) mice, while CD8+ T cells were substantially more enriched in the pancreas of KPC;Ulk1fl/fl mice than in control KPC mice, although the results were not statistically significant (Supplementary Fig. 5a–c). Here, MSR1 is linked to neoplasm.
