Maturation-dependent expression of AIM2 in human B-cells

Maturation-dependent expression of AIM2 in human B-cells

Intracellular DNA- and RNA-sensing receptors, such as the IFN-inducible protein Absent in Melanoma 2 (AIM2), serve as host sensors against a wide range of infections. Immune sensing and inflammasome activation by AIM2 has been implicated in innate antiviral recognition in many experimental systems using cell-lines and animal models. However, little is known about the expression and function of ...

Expression of Biologically Active Recombinant B-Domain-Deleted Human Factor VIII in Mammalian Cells

Human memory B cells originate from three distinct germinal center-dependent and -independent maturation pathways.

Multiple distinct memory B-cell subsets have been identified in humans, but it remains unclear how their phenotypic diversity corresponds to the type of responses from which they originate. Especially, the contribution of germinal center-independent responses in humans remains controversial. We defined 6 memory B-cell subsets based on their antigen-experienced phenotype and differential express...

Maturation-dependent expression and function of the CD49d integrin on monocyte-derived human dendritic cells.

Dendritic cells (DC) are highly specialized APC that are critical for the initiation of T cell-dependent immune responses. DC exert a sentinel function while immature and, after activation by inflammatory stimuli or infectious agents, mature and migrate into lymphoid organs to prime T cells. We have analyzed integrin expression on monocyte-derived DC (MDDC) and found that expression of CD49d in...

EXPRESSION OF HUMAN PROTEINASE 3 IN CHINESE HAMSTER OVARY CELLS (CHO-CELLS)

Proteinase 3(PR3) is a human polymorphonuclear leukocyte serine proteinase and is the main target antigen for antineutrophil cytoplasmic antibodies (ANCA) found in Wegener's granulomatosis (WG). We developed a stable expression system for conformationally intact recombinant PR3 (rPR3) in Chinese hamster ovary cells (CHO-cells). The part of PR3 cDNA that encoded the active form of PR3 was s...
