Inhibition of MCP-1 and MIP-2 transcription and translation by mimosine in muscle tissue infected with the parasite Trichinella spiralis.

Mimosine is a non-toxic plant aminoacid which is an effective inhibitor of DNA replication by acting at the S-phase. In this study we infected mice with T. spiralis, a nematode parasite, and studied the inflammatory response through the determination of MIP-2, a C-X-C chemokine and MCP-1, a C-C chemokine in the inflamed area around the parasitic cyst.

Vitamin B6-deficient diet plus 4-deoxypyridoxine (4-DPD) reduces the inflammatory response induced by T. spiralis in diaphragm, masseter and heart muscle tissue of mice.

Animals fed diets deficient in vitamin B6 develop microcytic anemia, alterations of growth, and other pathologies. 4-deoxypirydoxine is a potent antagonist of vitamin B6 coenzyme which depresses IL-1, TNF and IL-6 and has anti-inflammatory properties. The aim of this study was to show the anti-inflammatory effects of 4-DPD on chronic inflammation caused by the nematode parasite T.

IgG, IgG1 and IgM response in Trichinella spiralis-infected mice treated with 4-deoxypirydoxine or fed a Vitamin B6-deficient diet.

The aim of this study was to investigate the effect of pyridoxine (Vitamin B6) deficiency on the immunological response of BALB/c mice infected with the parasite T. spiralis. Specific anti-parasite IgM and IgG immunoglobulins were detected by ELISA method in the serum of treated animals at different periods for 60 days post infection.

Induction of monocyte chemotactic protein-1 (MCP-1) and TNF alpha by Trichinella spiralis in serum of mice in vivo.

MCP-1 is a small (8-10 KDa) protein and a prototype member of the CC chemokine beta subfamily, which plays a critical role in acute and chronic inflammation. Recent evidence suggests an important role for MCP- 1, MCP-2 and MCP-3 in a number of pathological states, including delayed type hypersensitivity conditions, parasitic infections and rheumatoid arthritis. Forty BALB-c mice were treated with the parasite Trichinella spiralis.
