Overview:
KDM4A or lysine (K)-specific demethylase 4A is a member of the Jumonji domain 2 (JMJD2) family that encodes a protein containing a JmjN domain, a JmjC domain, a JD2H domain, two TUDOR domains, and two PHD-type zinc fingers. KDM4A functions in euchromatin to remove histone methylation marks that are associated with active transcription (1). KDM4A also act as a trimethylation-specific demethylase those converting specific trimethylated histone residues to the dimethylated form, and as a transcriptional repressor (2).
Gene Aliases:
JMJD2A; JHDM3A; KIAA0677
Genbank Number:
BC002558

IgM是免疫球蛋白M(Immunoglobulin M,IgM)的缩写。根据结构的不同将免疫球蛋白分为五种,IgM是人的免疫球蛋白之一,其他还有lgA、lgG、IgD和lgE。
HSV1型导致的一般都是腰部以上的感染,典型症状是水泡有可能引起脑炎,而且有非活化状态的潜伏。所以我觉得你根本就不用担心这个抗体IgG阳性的化验单。
2-IgM也是一种特异性感染指标,但在人体内持续时间不长(有时是30天更短),往往是传染病的近期感染指标。呈阴性是指:你近期没有感染过结核杆菌。
