Wei et al developed a biomimetic self-propelling micromotor formulation for use as an oral antivirulence vaccine; the propulsion is provided by a magnesium-based core, and a biomimetic cell membrane coating is used to detain and neutralize a toxic antigenic payload; the resulting motor toxoids leverage their propulsion properties in order to more effectively elicit mucosal immune responses.

Plasma cells (PC) are found in the central nervous system of multiple sclerosis patients, yet their source and role in multiple sclerosis remains unclear. Rojas et al find that some PC in the central nervous system of mice with experimental autoimmune encephalomyelitis (EAE) originate in the gut and produce immunoglobulin A (IgA). Moreover, the researchers show that IgA + PC are dramatically reduced in the gut during EAE, and likewise, a reduction in IgA-bound fecal bacteria is seen in multiple sclerosis patients during disease relapse.
