Marginal Zone Theory...?

Question

Does anyone know anything about the marginal zone theory as the origin of agriculture. I either need to prove or disprove it. so any evidence for either argument would help.

thanks.

Answer 1

The marginal zone theory is actually the region at the interface between the non-lymphoid red pulp and the lymphoid white-pulp of the spleen. (Some sources consider it to be the part of red pulp which borders on the white pulp, while other sources consider it to be neither red pulp nor white pulp.)

The major role of marginal zone is to trap particulate antigen from the circulation and present the antigen to the lymphocytes of the spleen.

Experiments have shown that inert latex beads as well as live bacteria such as Escherichia coli and Listeria monocytogenes are trapped by the marginal zone. However, only immunogenic substances, ie. bacteria, are trafficked to the T and B cell zones of the white-pulp and are efficiently presented to elicit an immune response.
