Diagnostic significance of determining products of DNA rearrangments of the T-and-B cell receptor TREC/KREC in common variable immunodeficiency

Medical and Biological Problems of Life Activity
Common variable immunedeficiency (CVID) is a group of diseases that are inborn errors of the immune system and are characterized by impaired production of protective antibodies. The reason is a defect in the T- and B-cells, leading to impaired ability to

Monitoring of Immune Recovery After Hematopoietic Stem Cell Transplantation in Patients with Aplastic Anemia by Quantitative Determination of TREC and KREC

Journal of Human Immunity
Analysis of T- and B-lymphocyte recovery after hematopoietic stem cell transplantation (HSCT) is important for assessing the positive dynamics of treatment. Flow cytometry is informative enough to monitor immune recovery in the post-transplant period.
