Anti-glutathione S-transferase omega 1-1 (GSTO1-1) antibodies are increased during acute and chronic inflammation in humans.

Clin Exp Immunol 2022 Jun 22. Epub 2022 Jun 22.

Department of Translational Research NTMC, University of Pisa, Italy.

Glutathione S-transferase omega-1 (GSTO1-1) is a cytosolic enzyme involved in the modulation of critical inflammatory pathways as well as in cancer progression. Auto-antibodies against GSTO1-1 were detected in serum of patients with esophageal squamous cell carcinoma and were proposed as potential biomarkers in the early detection of the disease. Our data demonstrate that anti-GSTO1-1 antibodies can be found also in different types of inflammatory diseases, such as autoimmune rheumatoid arthritis and infectious SARS-CoV-2 and trichinellosis.

A Trichinella spiralis new born larvae-specific protein, Ts-NBL1, interacts with host's cell vimentin.

Parasitol Res 2022 May 23;121(5):1369-1378. Epub 2022 Mar 23.

UMR BIPAR, Anses, Laboratoire de Santé Animale, INRAE, Ecole Nationale Vétérinaire d'Alfort, Maisons-Alfort, France.

The parasitic nematode Trichinella has a special relationship with its host as it has a unique intracellular location within the feeder cell which is a structure derived from skeletal muscle fiber. It has been proposed that "parakines" secreted by Trichinella larvae serve as messengers to implement communication between the parasite and the muscle cells through a molecular cross-talk to ensure permanent coexistence within the host. The Ts-NBL1 protein is considered to be a potential key "parakine" involved in the early invasion of the muscle fiber and its transformation into a feeder cell during Trichinella spiralis infection.
