Deficiency Diseases

Adult dogs maintained on an artificial, balanced ration adequate in all dietary essentials as far as is known except water-soluble, heat-stable vitamin B2 (G) developed, after a sufficient time, a slowly progressive disease characterized by loss of weight, persistent vomiting and diarrhea, and marked muscular weakness, which ended fatally in from 200 to over 300 days. The clinical features of this condition, as pointed out in the discussion, are quite different from those characterizing the canine disease known as black tongue. The anatomic changes in this condition consist of marked demyelination of the peripheral nerves, including the vagus; degeneration of the medullary sheaths and replacement by gliosis of the posterior columns of the spinal cord, particularly the fasciculi graciles; degeneration of the medullary sheaths of the posterior and less often of the anterior nerve roots of the cord; occasionally slight degenerative changes in most of the other fiber tracts of the cord. Attention is called to the fact that degenerative lesions in the central nervous system similar or identical with these have frequently been described in pellagra in man.

Peptide Maps

Several classes of 10-nm filaments have been reported in mammalian cells and they can be distinguished by the size of their protein subunit. We have studied the distribution of these filaments in nerves from calves and other mammals. From the display on polyacrylamide electrophoretic gels of proteins in extracts from fibroblast and central, cranial and peripheral nerves, we cut the appropriate stained bands and prepared iodinated peptide maps. The similarities between the respective maps provide strong evidence for the presence of vimentin in cranial and peripheral nerves. The glial fibrillary acidic protein was found in axon preparations from the central nervous system, but was not identified in distal segments of some cranial nerves, nor in peripheral nerve.

Peripheral Immune Cells

Multiple sclerosis (MS), an immune-mediated demyelinating disease of the central nervous system (CNS), initially presents with a relapsing-remitting disease course. During this early stage of the disease, leukocytes cross the blood–brain barrier to drive the formation of focal demyelinating plaques. Disease-modifying agents that modulate or suppress the peripheral immune system provide a therapeutic benefit during relapsing-remitting MS (RRMS). The majority of individuals with RRMS ultimately enter a secondary progressive disease stage with a progressive accumulation of neurologic deficits. The cellular and molecular basis for this transition is unclear and the role of inflammation during the secondary progressive disease stage is a subject of intense and controversial debate. In this review article, we discuss the following main hypothesis: during both disease stages, peripheral immune cells are triggered by CNS-intrinsic stimuli to invade the brain parenchyma. Furthermore, we outline the different neuroanatomical routes by which peripheral immune cells might migrate from the periphery into the CNS.

The main milestones of the life and work of L.O. Darkshevich. It is noted that the work of a professor on the study of the pathology of muscles and peripheral nerves is of great interest. As early as 1903, in a German manual on pathological anatomy of the nervous system, Liverius Osipovich wrote a chapter on the pathological anatomy of muscles. We emphasize that later they wrote several articles on cerebral and arthropathic amiotrophies. Studying the question of the so-called retrograde degeneration of nerves, he pointed to the development of degenerative changes not only in the peripheral, but also in the central segment of the nerve, which is of great interest for clarifying the spread of the process. The article notes that Liveriy Osipovich Darkshevich considered the creation of a manual on nervous diseases as the greatest debt of his life, which was the testament of his late teacher — Professor A.Ya. Kozhevnikov, who had not managed to do this. Well aware of the conditioned reflex principles of the central nervous system, Liverii Osipovich attached special importance to the cerebral cortex as a body of mental activity. He pointed out that normal mental activity is formed under the influence of incessantly arriving stimuli of the external world, which, having reached the cerebral cortex and entering our consciousness, give rise to representations, the appearance of which in turn gives rise to the manifestation of active cortical activity-the emergence of volitional impulses. Liverii Osipovich was an ardent supporter of active disease therapy and was often an innovator in this field.

Integrin Alpha 6

Integrin alpha 6 beta 4 is expressed in human peripheral nerves, but not in the central nervous system. This integrin heterodimer has previously been found in perineural fibroblast-like cells and in Schwann cells (SCs), which both assemble a basement membrane but do not form hemidesmosomes. We show here that in SCs, which had formed a myelin sheath, alpha 6 beta 4 was enriched in the proximity of the nucleus, at Ranvier paranodal areas and at Schmitt-Lanterman clefts; alpha 6 beta 4 was also found at the grooved interface between small axons and non-myelinating SCs. Immunoprecipitation of human peripheral nerves, in combination with Western blotting showed that beta 4 is associated with the alpha 6A subunit. Northern blot analysis of human peripheral nerves showed a single beta 4 transcript of 6 kb. Using the reverse transcriptase polymerase chain reaction, we detected two mRNA species, one for the most common (−70, -53) form of beta 4 and the other encoding the (+53) variant of beta 4. Cultured SCs were devoid of alpha 6 beta 4 but expressed alpha 6 beta 1, indicating that SCs lose beta 4 expression when contact with neurons is lost. Thus, resting SCs in contact with axons express alpha 6A in combination with beta 4, irrespective of myelin formation. We suggest that alpha 6 beta 4 expressed in SCs plays a role in peripheral neurogenesis.
