Publication Open Access Lactiplantibacillus plantarum DSM20174 attenuates the progression of non-alcoholic fatty liver disease by modulating gut microbiota, improving metabolic risk factors, and attenuating adipose inflammation(MDPI, 2022) Riezu Boj, José I.; Barajas Vélez, Miguel Ángel; Pérez Sánchez, Tania; Pajares Villandiego, María Josefa; Araña Ciordia, Miriam; Milagro Yoldi, F. I.; Urtasun Alonso, Raquel; Ciencias de la Salud; Osasun ZientziakNon-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease, reaching epidemic proportions worldwide. Targeting the gut–adipose tissue–liver axis by modulating the gut microbiota can be a promising therapeutic approach in NAFLD. Lactiplantibacillus plantarum, a potent lactic-acid-producing bacterium, has been shown to attenuate NAFLD. However, to our knowledge, the possible effect of the Lactiplantibacillus plantarum strain DSM20174 (L.p. DSM20174) on the gut–adipose tissue axis, diminishing inflammatory mediators as fuel for NAFLD progression, is still unknown. Using a NAFLD mouse model fed a high-fat, high-fructose (HFHF) diet for 10 weeks, we show that L.p DSM20174 supplementation of HFHF mice prevented weight gain, improved glucose and lipid homeostasis, and reduced white adipose inflammation and NAFLD progression. Furthermore, 16S rRNA gene sequencing of the faecal microbiota suggested that treatment of HFHF-fed mice with L.p DSM20174 changed the diversity and altered specific bacterial taxa at the levels of family, genus, and species in the gut microbiota. In conclusion, the beneficial effects of L.p DSM20174 in preventing fatty liver progression may be related to modulations in the composition and potential function of gut microbiota associated with lower metabolic risk factors and a reduced M1-like/M2-like ratio of macrophages and proinflammatory cytokine expression in white adipose tissue and liver.Publication Open Access Pediococcus acidilactici pA1c® improves the beneficial effects of metformin treatment in type 2 diabetes by controlling glycaemia and modulating intestinal microbiota(MDPI, 2023) Cabello Olmo, Miriam; Oneca Agurruza, María; Urtasun Alonso, Raquel; Pajares Villandiego, María Josefa; Goñi Irigoyen, Saioa; Riezu Boj, José I.; Milagro Yoldi, F. I.; Ayo, Josune; Encío Martínez, Ignacio; Barajas Vélez, Miguel Ángel; Araña Ciordia, Miriam; Ciencias de la Salud; Osasun ZientziakType 2 diabetes (T2D) is a complex metabolic disease, which involves maintained hyperglycemia, mainly due to the development of an insulin resistance process. Metformin administration is the most prescribed treatment for diabetic patients. In a previously published study, we demonstrated that Pediococcus acidilactici pA1c® (pA1c) protects from insulin resistance and body weight gain in HFD-induced diabetic mice. The present work aimed to evaluate the possible beneficial impact of a 16-week administration of pA1c, metformin, or the combination of pA1c and metformin in a T2D HFD-induced mice model. We found that the simultaneous administration of both products attenuated hyperglycemia, increased high-intensity insulin-positive areas in the pancreas and HOMA-β, decreased HOMA-IR and also provided more beneficial effects than metformin treatment (regarding HOMA-IR, serum C-peptide level, liver steatosis or hepatic Fasn expression), and pA1c treatment (regarding body weight or hepatic G6pase expression). The three treatments had a significant impact on fecal microbiota and led to differential composition of commensal bacterial populations. In conclusion, our findings suggest that P. acidilactici pA1c® administration improved metformin beneficial effects as a T2D treatment, and it would be a valuable therapeutic strategy to treat T2D.
