WebJan 17, 2024 · NK cells play an important role in the innate defenses against tumor growth and metastases. Human NK cell activation and function are regulated by an array of HLA class I-specific inhibitory receptors and activating receptors recognizing ligands expressed de novo on tumor or virus-infected cells. NK cells have been exploited in immunotherapy … WebApr 9, 2024 · This activation gives C1s enzymatic activity to cleave complement protein C4 into C4a and C4b (see Figure 11.3 B. 2 A and Figure 11.3 B. 2 B). 3. C2 then binds to C4b and is cleaved by C1 into C2a and C2b (see Figure 11.3 B. 3 A and Figure 11.3 B. 3 B). 4. C4b and C2a combine to form C4b2a, the C3 convertase.
