Overview. Posttransplant lymphoproliferative disease (PTLD) is an unusual entity that has many features of an immune system malignancy. It is characterized by uncontrolled proliferation of lymphoid lineage cells (typically B cells, rarely non-B lineage) in a context of posttransplant immunosuppression.
A top-level domain, or TLD, is the most generic part of a domain name and one that all domain names require. The most common TLDs are: . 1 com. .net.. 2 org. . 3 edu.eneric TLDs or gTLDs. Generic TLDs (gTLD) are top-level domains that are not related to a specific country. There are dozens of gTLDs for various purposes. Some are restricted and some are not.
