Cell-based tolerogenic therapy is a promising approach for the treatment of autoimmune diseases and transplant rejection. Regulatory T cells and tolerogenic dendritic cells have been particularly explored in the treatment of various autoimmune disorders in experimental models of disease. Although some of these cells have already been tested in a limited number of clinical trials, there is still a need for preclinical research on tolerogenic cells in animal models of autoimmunity. This review will focus on the relevance of data obtained from studies in experimental animal models for the use of tolerogenic cell-based therapy in humans. Also, perspectives for further improvement of tolerogenic cell preparation towards enhanced suppressive activity and stability of the cells will be discussed.

Background: Several clinical studies have demonstrated that Helicobacter pylori (Hp) infection may exacerbate the progression of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD); however, the underlying mechanisms remain unclear. This study aims to investigate the characterization of the gastric microbiome and metabolome in relation to the progression of MASLD induced by Hp infection.
Methods: We established a high-fat diet (HFD) obese mouse model, both with and without Hp infection, to compare alterations in serum and liver metabolic phenotypes.

Enterohemorrhagic (EHEC), a pathotype within the Shiga toxin-producing (STEC) group, is a major etiological agent of severe gastrointestinal illness and life-threatening sequelae, including hemolytic uremic syndrome. Although insights into EHEC pathogenesis have been gained through traditional 2D cell culture systems and animal models, these platforms are limited in their ability to recapitulate human-specific physiological responses and tissue-level interactions. Recent progress in three-dimensional (3D) cell culture systems, such as spheroids, organoids, and organ-on-a-chip (OoC) technologies, has enabled more physiologically relevant models for investigating host-pathogen dynamics.

Infantile Epileptic Spasms Syndrome (IESS), also referred to as West syndrome, is a severe epileptic disorder that emerges during early childhood. It is marked by characteristic epileptic spasms, developmental stagnation or regression, and a distinctive electroencephalogram (EEG) pattern known as hypsarrhythmia. To better understand the underlying mechanisms of IESS, various genetic and chemically induced animal models have been developed.

It has been recently described the Congenital Zika Syndrome (CZS). Children from pregnant women who were infected by the virus have expressed a set of symptoms, particularly involving neurological disorders such as microcephaly. Animal models have been conducted aiming to enhance the knowledge about the CZS and giving support for future studies proposing prevention and treatment for this condition.

Objective: Previous studies in our lab demonstrated that estrogen receptor-α (ERα) levels in cartilage decreased with osteoarthritis (OA). We also defined the essential role of ERα in maintaining the health of chondrocytes. However, most of the studies were conducted in vitro, and the physiological link between ERα loss and cartilage degradation has not been demonstrated using animal models.
