We show here active clustering of TCR–MHC molecules at the immune synapse after interaction between aAPC and T cells. This multivalent system allows identification and stimulation of antigen ...

Only this time the antigen is whole and B cells don't keep it to themselves ... exclusion of negative regulators such as CD45 and the stimulation of actin polymerization (Fig.

Immune cells are generated to keep our bodies healthy. To combat disease, our bodies initiate two separate waves of immunity.

Imagine a super-charged immune cell that can launch a focused attack on stubborn solid tumors—a smart fighter that destroys ...

An antigen is any substance that can spark ... Some communicate with other cells, and some stimulate B cells to produce more antibodies. Others attract more T cells or cell-eating phagocytes.

Rutgers Health researchers have discovered that networks of misplaced immune cells drive an aggressive lung disease, ...

Use the purifier to isolate the hepatitis B antigen produced by the yeast cells. The vaccine, once administered, will stimulate the immune system to attack the antigen (i.e., the protein coat).

which triggers 4-1BB signaling to stimulate NK cell proliferation and IFN-γ secretion. 4-1BBL is often co-administered with other cytokines to enhance the activation of NK cells. 3. Augment DC antigen ...
