Inside-out signaling regulation of the beta2-integrin leukocyte function-associated antigen-1 (LFA-1) by different cytoplasmic proteins, including 14-3-3 proteins, is essential for adhesion and migration of immune cells. Here, we identify a new pathway for the regulation of LFA-1 activity by Cbl-b, an adapter molecule and ubiquitin ligase that modulates several signaling pathways. Cbl-b-/- mice...

Hematopoietic stem cell transplantation is a promising curative therapy for many combined primary immunodeficiencies and phagocytic disorders. We retrospectively reviewed pediatric cases of patients diagnosed with primary immunodeficiencies and scheduled for hematopoietic stem cell transplantation. We identified 22 patients (median age, 6 months; age range, 1 month to 10 years) with various dia...

Abstract Background To investigate the microRNA (miRNA)-gene interactions underlying leukocyte functions and characteristics, especially potential serum biomarkers, implicated in traditional Chinese medicine (TCM)-defined Pi-qi-deficiency syndrome (PQDS) Pi-wei damp-heat (PDHS) resulting from chronic atrophic gastritis (CAG). Methods Using RNA/miRNA-sequencing approach, compared with healthy co...

There are three major types of VWD disease. Type 1, the most frequent form, is characterized by a partial quantitative deficiency in von Willebrand factor (VWF). Type 2 is a qualitative deficiency, and Type 3 is a virtually complete deficiency. Type 2 VWD is divided into four subtypes. Type 2A includes variants with decreased platelet adhesion caused by a selective deficiency in high-molecular ...

s:3604:"During pregnancy, the placenta delivers "cord blood" to the baby through the umbilical cord serving as a lifeline of nourishment from the mother to baby. At birth, "cord blood" remains in the umbilical cord and placenta and until recently, had typically been discarded. The tragedy of this practice is that "cord blood" contains very special cells called "stem cells". Recent advances in m...

the charts of 27 patients with kawasaki disease (kd) admitted to nemazee hospital in shiraz from january 1991 to october 1998 were reviewed to identify the results of mean peroxidase index (mpxi) values, a measure of neutrophil staining intensity, obtained by the technicon hi analyzer (technicon instruments corp., tarrytown, ny) within the first 10 days of the illness 2 separate groups of patie...

Wiskott-Aldrich syndrome (WAS) is a primary immunodeficiency that manifests as increased susceptibility to many pathogens. Although the spectrum of infections suffered by WAS patients is consistent with defects in neutrophil (PMN) function, the consequences of WAS protein (WASp) deficiency on this innate immune cell have been unclear. We report that deficiency of WASp in both human and murine P...
