Systemic lupus erythematosus (SLE) is an autoimmune disease, the pathophysiology and genetic basis of which are incompletely understood. Using a forward genetic screen in multiplex families with SLE, we identified an association between SLE and compound heterozygous deleterious variants in the non-receptor tyrosine kinases (NRTKs) and . Experimental blockade of ACK1 or BRK increased circulating autoantibodies in vivo in mice and exacerbated glomerular IgG deposits in an SLE mouse model.

November 2024

Department of Diabetes and Endocrinology, Guy's and St Thomas' NHS Foundation Trust, London, UK.

Background: Pre-gestational diabetes occurs in approximately 1% of pregnancies in the UK and increases the risk of adverse maternal and fetal outcomes. More women with type 2 than type 1 diabetes are now becoming pregnant and tend to have higher rates of obesity and other multi-morbidities. Chronic kidney disease (CKD) affects approximately 5%-10% of pregnant women with type 1 diabetes and about 2%-3% with type 2 diabetes.

Article Synopsis
  • - The study explores the link between chronic kidney disease (CKD) and periodontal disease, proposing that changes in saliva and oral microbiota due to CKD could initiate periodontal disease rather than the other way around.
  • - Using animal models, researchers found that kidney disease led to a significant reduction in alveolar bone height and caused changes in salivary biochemistry and oral microbiota composition, resulting in a dysbiotic environment.
  • - Findings suggest that interactions between oral bacteria and the systemic conditions of CKD can exacerbate periodontal issues, as co-housing healthy rats with those having kidney disease improved periodontal health, while transferring diseased microbiota caused periodontal disease in healthy mice.
