Abstract Arsenic trioxide (As2O3), a kind of pentavalent arsenic, has recently been linked to disrupted immune function. Heat shock proteins (Hsps), a group of highly conserved proteins, are rapidly synthesised when living organisms are exposed to various stress conditions. The objective of this study is to determine the effects of As2O3 on the expression level of Hsps (Hsp90, Hsp70, Hsp60, Hsp40 and Hsp27) in the immune organs (spleen, thymus and bursa of Fabricius (BF)) of chickens. A total of 72 1-day-old male Hy-line chickens were randomly divided into four groups, including the low-As group (L group), middle-As group (M group), high-As group (H group) and control group (C group). Immune organs were collected, and levels of Hsp messenger RNA (mRNA) and protein were examined on days 30, 60 and 90. The results showed that the levels of Hsp mRNA (Hsp90, Hsp70, Hsp60, Hsp40 and Hsp27) and protein (Hsp70 and Hsp60) expression were significantly increased (p
