嗜硷细胞起源于骨髓,一般存在于骨髓及血液中,但现已证明,在许多迟缓过程超敏感性应答(delayed time-course hypersensitivity responses)时,它们可以按特殊的免疫学方式从血流中被召募进入到组织中。此反应如发生于皮肤则称之为皮肤嗜硷细胞超敏反应(cutaneous bas Alkaloid cells, which originate in the bone marrow and are commonly found in the bone marrow and in the blood, have now been shown to delay specific immune processes from many bloodstreams during many delayed, time-course hypersensitivity responses To be recruited into the organization. This reaction, if it occurs in the skin, is called cutaneous basal hypersensitivity
