Multiple Sclerosis (MS) is an autoimmune inflammatory disease that presents clinically with a range of symptoms including motor, sensory, and cognitive dysfunction as well as demyelination and lesion formation in brain and spinal cord. A variety of animal models of MS have been developed that share many of the pathological hallmarks of MS including motor(More)
The effect of a 24-h maternal deprivation at day 3 was studied on the hypothalamus-pituitary-adrenal axis of 18-day-old Brown Norway pups, whose stress-hyporesponsive period is similar to other rat strains. Deprivation resulted at day 18 in reduced basal ACTH levels. The rate of onset and the duration of stress-induced ACTH release were enhanced. CRH mRNA,(More)
Pediocin PA-1 is a bacteriocin which is produced by Pediococcus acidilactici PAC1.0. We demonstrate that pediocin PA-1 kills sensitive Pediococcus cells and acts on the cytoplasmic membrane. In contrast to its lack of impact on immune cells, pediocin PA-1 dissipates the transmembrane electrical potential and inhibits amino acid transport in sensitive cells.(More)
Bacteriophage p2 belongs to the most prevalent lactococcal phage group (936) responsible for considerable losses in industrial production of cheese. Immunization of a llama with bacteriophage p2 led to higher titers of neutralizing heavy-chain antibodies (i.e., devoid of light chains) than of the classical type of immunoglobulins. A panel of p2-specific(More)
Proline iminopeptidase produced by Propionibacterium shermanii plays an essential role in the flavor development of Swiss-type cheeses. The enzyme (Pip) was purified and characterized, and the gene (pip) was cloned and expressed in Escherichia coli and Lactococcus lactis, the latter species being an extensively studied, primary cheese starter culture that(More)
Various maturation forms of the plant protein thaumatin were expressed in yeast, using a promoter fragment of the glyceraldehyde- 3P -dehydrogenase (GAPDH) gene. Plasmids encoding preprothaumatin were shown to direct the synthesis of a processed form of the plant protein. The important role of signal sequences in the expression of the plant protein in yeast(More)
