WebNov 1, 2024 · Mannans, in yeast are the second major polysaccharides of the yeast cell wall. Yeast mannan (YM) comprises approximately 40% of the yeast cell wall dry mass. YM also occur connected to phosphorous, as phosphomannans and the quantity varies from 0.04–4.4% [19, 20]. WebAbstract Innate recognition of fungi leads to strong adaptive immunity. Investigators are trying to exploit this observation in vaccine development by combining antigens with evolutionarily conserved fungal cell wall carbohydrates to induce protective responses.
