Sickle cell disease (SCD) is an autosomal recessive genetic disorder. It is the most frequent structural hemoglobinopathy worldwide, and it is produced by an alteration in the globin chain genes. In Chile, there is no data on the prevalence of SCD since it is considered a very rare condition. The incidence of this disease has been increasing due to migration of people from areas with greater presence of SCD. It is important to know and consider this diagnosis in a selected group of patients with anemia, in order to prevent and treat the different complications of this disease. This article reviews the most recent information that shows new concepts in the knowledge of the physiopathology, and especially publications of guidelines and consensus in relation to the diagnosis and management of this con dition.

Donor-specific antibodies (DSAs) are essential causes of graft rejection in haploidentical hematopoietic stem cell transplantation (haplo-HSCT). DSAs are unavoidable for some patients who have no alternative donor. Effective interventions to reduce DSAs are still needed, and the cost of the current therapies is relatively high.

Mesenchymal stem cells (MSCs) are pluripotent stem cells with self-renewal. They play a critical role in cell therapy due to their powerful immunomodulatory and regenerative effects. Recent studies suggest that one of the key therapeutic mechanisms of MSCs seems to derive from their paracrine product, called extracellular vesicles (EVs).

Patients with spinal cord injury (SCI) may develop depression, which can affect their rehabilitation. However, the underlying mechanism of depression in SCI patients remains unclear. Previous studies have revealed increased p38 MAPK phosphorylation in the rat hippocampus after SCI, accompanied by depression-like behaviors.

Nuclear factor of activated T-cells 5 (NFAT5) is a transcription factor known for its role in osmotic stress adaptation in the renal inner medulla, due to the osmotic gradient that is generated between the renal cortex and renal inner medulla. However, its broader implications in kidney injury and chronic kidney disease (CKD) are less understood. Here we used two different Cre deleter mice (Ksp1.
