Lactoferrin Restores the Deoxynivalenol-Impaired Spermatogenesis and Blood-Testis Barrier Integrity via Improving the Antioxidant Capacity and Modifying the Cell Adhesion and Inflammatory Response. Antioxidants (Basel) 2023; 12:antiox12010152. [PMID: 36671014 PMCID: PMC9855165 DOI: 10.3390/antiox12010152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 12/12/2022] [Accepted: 01/04/2023] [Indexed: 01/11/2023] Open
Abstract
Deoxynivalenol (DON) is among the most prevalent contaminants in cereal crops and has been demonstrated to impair male spermatogenesis and induce oxidative stress, testicular apoptosis, and disruption of the blood-testis barrier (BTB). Lactoferrin (LF) is an iron-binding glycoprotein with multifunctions including anti-inflammation and antioxidation. Thus, this study aimed to investigate the effects of LF on the spermatogenesis and integrity of the BTB in DON-exposed mice. Thirty-two male mice were allotted to four groups for a 35-day feeding period: vehicle (basal diet), DON (12 mg/kg), LF (10 mg/d, p.o.), and DON + LF. The results showed that DON induced vacuolization of the spermatogenic epithelium, broke the adhesion junction between Sertoli cells and spermatids established by N-cadherin and induced testicular oxidative stress. LF administration restored sperm production, attenuated the DON-induced oxidative stress and reduced the breakages in adhesion junction. DON exposure enhanced the protein expression of occludin. Transcriptional profiling of the testis observed a disturbance in the expression profiles of cell adhesion and inflammatory response genes, and LF administration reversed these gene expressions. Furthermore, down-regulated signaling pathways, including the apical junction, TNFα signaling via NF-κB, and TGF-β in the DON group were observed. These were restored by LF. Enrichment analysis between DON + LF group and vehicle also confirmed the absence of these pathways. These findings indicated that LF eliminated the DON-induced detriment to spermatogenesis and cell connections between Sertoli cells and spermatids via improving antioxidant capacity and modifying the inflammatory response and cell adhesion genes.

Liu D, Wang Q, He W, Ge L, Huang K. Deoxynivalenol aggravates the immunosuppression in piglets and PAMs under the condition of PEDV infection through inhibiting TLR4/NLRP3 signaling pathway. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 231:113209. [PMID: 35051765 DOI: 10.1016/j.ecoenv.2022.113209] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 01/07/2022] [Accepted: 01/13/2022] [Indexed: 06/14/2023]
Abstract
Mycotoxins are toxic metabolites produced by fungi, which are ubiquitous in cereals and feed worldwide and threaten human and animal health. Deoxynivalenol (DON) is one of the most prevalent mycotoxins and causes a series of toxicities, especially enterotoxicity and immunotoxicity. Porcine epidemic diarrhea virus (PEDV) is a destructive enteropathogenic animal coronavirus, is often accompanied with DON contamination in the swine herd. Previous studies have shown that PEDV infection leads severe immunosuppression in pigs. However, whether DON exposure aggravates the PEDV-induced immunosuppression remains unclear. In this study, weaned piglet and porcine alveolar macrophage cell (PAM) models were established to explore the effects of DON on the PEDV-induced immunosuppression and to clarify its underlying mechanism. The in vivo results showed that 2.25 mg/kg feed DON significantly exacerbated the immunosuppressive effects on the PEDV-infected piglets, as demonstrated by the decreases in growth performance, the numbers of goblet cells and CD3+T cells, as well as the protein expressions of ZO-1, Claudin1 and Muc2, in addition to the increases in anti-inflammatory factors levels and the intestinal injury. Similarly, the in vitro results demonstrated that 3-4 μM DON markedly aggravated apoptosis, enhanced the expressions of anti-inflammatory factors, but reduced the migration and phagocytosis abilities of the PEDV-infected PAMs. Furthermore, DON significantly suppressed the expressions of TLR4/NLRP3 in vivo and in vitro. To contrast, lipopolysaccharide (LPS), the corresponding activator, obviously alleviated the DON-exacerbated immunosuppression. Our findings suggest that DON could aggravate host immunosuppression under the condition of PEDV infection through inhibiting TLR4/NLRP3 signaling pathway, and provide novel theoretical insights into the further studies on the immunotoxicity of DON contamination and PEDV-induced immunosuppression.

Abstract
Deoxynivalenol (DON) is an unavoidable cereal crops contaminants and environmental pollutants, which seriously threated the health of human and animal. DON has been reported to exert significant toxicity effects on spermatogenesis, but the underlying mechanisms remain largely inconclusive. The blood-testis barrier (BTB) provides a specialized biochemical microenvironment for maintaining spermatogenesis. Thus, we hypothesized that DON could impair BTB and lead to spermatogenesis disorder. To confirm this hypothesis, sixty male mice were intragastrically administered with 0, 1.2, 2.4 and 4.8 mg/kg body weight DON for 28 days, and several important observations were obtained in present study. First, we found that DON induced spermatogenesis disorder, reflected by the declines of sperm concentration and quality, sperm ultrastructural damage as well as seminiferous tubular damage. Then, we proved that DON induced BTB disruption as well as decreased the expressions of BTB junction proteins, including Occludin, Connexin 43 and N-cadherin. Finally, the present study showed that DON induced inflammation and inhibited T biosynthesis in testis of mice. These results revealed that DON induced spermatogenesis disorder by BTB disruption associated with testosterone deficiency and inflammation in mice, which shed a new light on the potential mechanisms of reproductive toxicity induced by DON.
