Arsenic is decreased in target organs during viral infection in mice.

Arsenic (As), a potentially toxic trace element, has been shown to influence viral replication and resistance to microbial infection. However, the impact of infection on the normal As status in target organs involved in the disease process has not been studied to date. In the present study, As was measured through inductively coupled plasma mass spectrometry in the plasma, liver, spleen, kidney, heart, pancreas and brain at days 1 and 3 of coxsackievirus B3 infection in female Balb/c mice.

Sequential changes in Fe, Cu, and Zn in target organs during early Coxsackievirus B3 infection in mice.

In Coxsackievirus B3 (CB3) infection, the heart and pancreas are major target organs and, as a general host response, an associated immune activation and acute phase reaction develops. Although iron (Fe), copper (Cu), and zinc (Zn) are involved in these responses, sequential trace element changes in different target organs of infection have not been studied to date. In the present study, Fe, Cu, and Zn were measured through inductively coupled plasma mass spectrometry (ICP-MS) in the plasma, liver, spleen, heart, and pancreas during the early phase (d 1 and 3) of CB3 infection in female Balb/c mice.

Trace element changes in the pancreas during viral infection in mice.

Introduction: The trigger for some cases of juvenile diabetes has been suggested to be an interaction between a virus and various trace elements. Infection with human coxsackievirus B3 (CB3) in the murine model results in viral replication and inflammation in the pancreas.

Aim: To determine how infection affects the trace element balance in the pancreas.
