The effect of mitochondria-targeted antioxidant 10-(6'-plastoquinonyl) decyltriphenylphosphonium bromide (SkQ1) and its fragment dodecyltriphenylphosphonium (C12TPP), weak uncouplers of respiration and oxidative phosphorylation, was studied using a mouse model of carrageenan-induced acute inflammation in the subcutaneous air pouch. In our model, SkQ1 demonstrated a strong anti-inflammatory effect that manifested in a decrease in the absolute number of inflammatory cells, mainly neutrophils, and their relative number in parallel with an increase in macrophages and mast cell content in the inflammatory exudate. The concentration of proinflammatory cytokine IL-6 in the exudate also tended to decrease. C12TPP produced no significant effect on the inflammation process.

Diabetes is one of the most prevalent metabolic disorders, and its incidence has been experiencing a steady annual rise in recent years. Diabetic peripheral neuropathy (DPN) represents the most frequent adverse complication, exerting a profound impact on the quality of life for those suffering from diabetes. The etiology of DPN is complex, including impaired mitochondrial function.

Spermatozoa cryopreservation has been widely used for animal genetic conservation. Despite advances in chicken semen cryopreservation, the mechanism of spermatozoa cryodamage remains to be revealed. The cryopreservation process induces motion parameter decreased, structure damaged, proteomic and antioxidant system remodeled in spermatozoa.

Low-temperature preservation of yak semen during transportation and conservation is crucial to accelerate yak breeding. The effects of low-temperature cooling on yak semen quality, however, are poorly understood. This study aimed to determine the dose-dependent effect of mitochondria-targeted antioxidant "MitoQ" on the motility, oxidative status, and mitochondrial function of yak semen during low-temperature preservation.

Objective: Ovarian tissue cryopreservation has become a promising alternative for fertility preservation in cancer patients, allowing ovarian tissue to be stored for future autotransplantation. Oxidative stress damage occurring during the cryopreservation process may impact tissue quality and function. This study aims to investigate the protective effects and potential mechanisms of Mitoquinone (MitoQ), a mitochondria-targeted derivative of the antioxidant ubiquinone, during the vitrification of ovarian tissue in mice.

Autoimmune uveitis is a relapsing blind-causing ocular condition with complex pathogenesis that is not completely understood. There is a high demand for accurate animal models of experimental autoimmune uveitis (EAU) suitable for elucidating the molecular mechanisms of the disease and testing new therapeutic approaches. Here, we demonstrated that photoreceptor Ca/Zn-sensor protein recoverin is a uveoretinal antigen in albino rabbits provoking typical autoimmune chorioretinitis 2-4 weeks after immunization.
