Connecting autoimmune disease to Bardet-Biedl syndrome and primary cilia.

ABSTRACT

Bardet-Biedl syndrome (BBS) is a genetic disorder caused by the dysfunction of the primary cilium. To date, immunological defects in the disease have not been systematically assessed. In this issue, Tsyklauri and colleagues find, through detailed analysis of BBS mutant animals, that B-cell development is altered in mutant mice (Tsyklauri et al, 2021). The authors further report that BBS patients are more susceptible to autoimmune disorders. This study sheds new light on the potential role of primary cilia in controlling immune function in disease.
