S-acylation and lipid exchange at the ER-Golgi membrane contact sites regulate pathogen entry in human cells

Cells have evolved endocytic pathways to internalize different molecules, to regulate intra-cellular communication and their interaction with external environment. Pathogens have co-evolved with cells to exploit these processes for infections. In particula ...

Clathrin-associated AP-1 control stermination of STING signalling

Sophie Marie Elisabeth Rivara, Andrea Ablasser, Jonathan Jean-Pierre Ricci, Ying Liu, Pengbiao Xu, Chong Liu

Stimulator of interferon genes (STING) functions downstream of cyclic GMP-AMP synthase in DNA sensing or as a direct receptor for bacterial cyclic dinucleotides and small molecules to activate immunity during infection, cancer and immunotherapy(1-10). Prec ...

Investigating the Biological Mechanisms underlying the Initiation of Autoimmunity against Beta Cell Antigens in Type 1 Diabetes

Chiara Cianciaruso

Type 1 diabetes (T1D) is an autoimmune disease characterized by circulating autoantibodies, lymphocytic infiltration of pancreatic islets of Langerhans, and cell-specific destruction of beta cells, leading to insulin deficiency and symptomatic hyperglycemi ...

Aberrant Accumulation of the Diabetes Autoantigen GAD65 in Golgi Membranes in Conditions of ER Stress and Autoimmunity

Jeffrey Alan Hubbell, Miriella Carmela Pasquier, Steinunn Baekkeskov Hanahan, Edward Allen Phelps, Chiara Cianciaruso

Pancreatic islet β-cells are particularly susceptible to endoplasmic reticulum (ER) stress, which is implicated in β-cell dysfunction and loss during the pathogenesis of type 1 diabetes (T1D). The peripheral membrane protein GAD65 is an autoantigen in huma ...

Mechanisms of pathogen entry through the endosomal compartments

Françoise Gisou van der Goot Grunberg

Several pathogens - bacteria, viruses and parasites - must enter mammalian cells for survival, replication and immune-system evasion. These pathogens generally make use of existing cellular pathways that are designed for nutrient uptake, receptor downregul ...
