Data on environmentally relevant level of aflatoxin B1-induced human dendritic cells' functional alteration

Abstract

We assessed the effects of naturally occurring levels of AFB1 on the expression of key immune molecules and function of human monocyte-derived dendritic cells (MDDCs) by cell culture, RT-qPCR, and flow cytometry. Data here revealed that an environmentally relevant level of AFB1 led to remarkably weakened key functional capacity of DCs, up-regulation of key transcripts and DCs apoptosis, down-regulation of key phagocytic element, CD64, and creation of pseudolicensing direction of DCs. Flow cytometry data confirmed a damage towards DCs, i.e., increased apoptosis. The detailed data and their mechanistic effects and the outcome are available in this research article (Mehrzad et al., 2018) [1]. The impaired phagocytosis capacity with triggered pseudolicensing direction of MDDCs caused by AFB1 and dysregulation of the key functional genes could provide a mechanistic explanation for the observed in vivo immunotoxicity associated with this mycotoxin.
