Diploid strains of the budding yeast Saccharomyces cerevisiae change the pattern of cell division from bipolar to unipolar when switching growth from the unicellular yeast form (YF) to filamentous, pseudohyphal (PH) cells in response to nitrogen starvation. The functions of two transmembrane proteins, Bud8p and Bud9p, in regulating YF and PH cell polarity(More)
In Saccharomyces cerevisiae, diploid yeast cells follow a bipolar budding program, which depends on the two transmembrane glycoproteins Bud8p and Bud9p that potentially act as cortical tags to mark the cell poles. Here, we have performed systematic structure-function analyses of Bud8p and Bud9p to identify functional domains. We find that polar transport of(More)
Multiple sclerosis (MS) is a chronic inflammatory disease of the CNS which leads to demyelination, axonal destruction and neuronal loss in the early stages. Available therapies mainly target the inflammatory component of the disease but fail to prevent neurodegeneration. To investigate the effect of ciliary neurotrophic factor (CNTF) on the survival of(More)
Axonal destruction and neuronal loss occur early during multiple sclerosis, an autoimmune inflammatory CNS disease that frequently manifests with acute optic neuritis. Available therapies mainly target the inflammatory component of the disease but fail to prevent neurodegeneration. To investigate the effect of minocycline on the survival of retinal ganglion(More)
Axonal destruction and neuronal loss occur early during multiple sclerosis (MS), an autoimmune inflammatory central nervous system disease that frequently manifests with acute optic neuritis. Glatiramer acetate (GA) and interferon-beta-1b (IFN-beta-1b) are two immunomodulatory agents that have been shown to decrease the frequency of MS relapses. However,(More)
In Saccharomyces cerevisiae, the transcription factors Tec1p and Ste12p are required for haploid invasive and diploid pseudohyphal growth. Tec1p and Ste12p have been postulated to regulate these developmental processes primarily by cooperative binding to filamentous and invasion-responsive elements (FREs), which are combined enhancer elements that consist(More)
In multiple sclerosis (MS), post-mortem studies of human brain tissue as well as data from animal models have shown that apoptosis of neurons occurs to a significant extent during this disease. As neurodegeneration in MS correlates with permanent neurological deficits in patients, understanding the mechanisms would be an important pre-condition for(More)
