Are elevated peripheral blood natural killer cells effectively downregulated by immunoglobulin G infusion in women with recurrent spontaneous abortions?
Downregulation of NK cells in women with RSA is associated with a favorable pregnancy outcome. Peripheral blood NK cells (CD56+, CD56+/16+) are effectively suppressed after IVIg therapy. Women with RSA and high NK cells benefit from IVIg therapy and experience suppression of CD56+ and CD56+/16+ NK cells.
NBI could be a useful tool for obtaining free resection margins in oral and oropharyngeal carcinoma.
