Murine cryptocococcal pulmonary infection elicited serum immunoglobulin M (IgM) and IgG to the capsular polysaccharide, but only IgG stained yeast cells in alveoli. Both isotypes produced punctuate immunofluorescence patterns on yeast cells like those of nonprotective antibodies. The difficulties involved in associating humoral immunity with protection in murine cryptocococcal infection could reflect nonprotective antibody responses.
小鼠隐球菌肺部感染可引发针对荚膜多糖的血清免疫球蛋白M(IgM)和IgG,但只有IgG能对肺泡中的酵母细胞进行染色。这两种同种型在酵母细胞上产生的点状免疫荧光模式与非保护性抗体的模式相似。在小鼠隐球菌感染中,将体液免疫与保护作用联系起来所涉及的困难可能反映了非保护性抗体反应。
