T119 |
0-223 |
Sentence |
denotes |
The immunobiology of FcγR is studied and understood almost exclusively in the context of hematopoietic cell function but relatively recent investigations have identified and explored FcγR expression on nonhemopoietic cells. |
T120 |
224-328 |
Sentence |
denotes |
These studies suggest important roles in normal immune function and in the MOA of some therapeutic mAbs. |
T121 |
329-487 |
Sentence |
denotes |
The most extensively characterized receptor expression is FcγRIIb which is expressed on follicular dendritic cell, airway smooth muscle and liver endothelium. |
T122 |
488-878 |
Sentence |
denotes |
Its abundant expression on liver sinusoidal endothelial cells (LSECs) is estimated to represent the majority of in vivo FcγRIIb expression.17, 29, 30, 31 As FcγRIIb lacks intrinsic proinflammatory signaling function, its role on these nonhemopoietic cells involves immune complex handling without the danger of, or the need for, induction of local tissue destructive inflammatory responses. |
T123 |
879-1216 |
Sentence |
denotes |
On LSEC its major role appears to be immune complex sweeping, a process of removal of small immune complexes such as opsonized virus or macromolecules.17 This scavenging role by FcγRIIb on LSEC can be exploited in principle by mAbs forming small soluble complexes with their targets such as antiviral, anticytokine or similar antibodies. |
