In contrast to T cells, in different immunopathologies, the brain provides a fostering environment to B cells. Primary central nervous system (CNS) lymphomas are usually of B cell origin. The cerebrospinal fluid (CSF) of patients with chronic infections and autoimmune diseases of the CNS typically contains remarkably stable oligoclonal Ig bands. In the CNS of multiple sclerosis patients, clonaUy expanded B cells and plasma cells persist. Ectopic B cell follicles develop in the meninges of patients with secondary progressive MS, and B cell differentiation may be recapitulated in the CNS of MS patients (Krumbholz et al., 2006) (see Chapters 18-24).

Some of the functions of lipids are related to the structures they form. The micelle formation characteristic of fatty acids, detergents, and soaps in aqueous solution helps to dissolve dirt and other hydrophobic materials. Lipid bilayers play many vital roles. Liposomes are used to deliver drugs to desired tissues. A cell membrane, because of its hydrophobic core, is a substantial barrier to the passage of ions, allowing the cell interior to have concentrations of ions different from those of the extracellular environment. Bilayers are good electrical insulators, and aid in the transmission of nerve impulses along the conducting portions of nerve fibers. The importance of fipids in neural function is seen in diseases in which these insulators are lost, such as multiple sclerosis, or not properly maintained, such as Tay-Sachs disease. 

In parallel with the continuous development of innovative robotic systems, in order to promote their use it is also crucial to provide an extensive evaluation of efficacy, safety, reliability, and users and families acceptance of the developed systems. The MUNDUS system was evaluated on six end users affected by neuromotor disorders (three spinal cord injuries, one multiple sclerosis, and two Friedreich s ataxia), and a high level of usability, user satisfaction, and motor performance were observed [125]. In the future, more trials conducted in natural environments are needed. Last but not least, to increase accessibility both investment and maintenance costs need to be reduced.
