What is the main purpose of using peptibody proteins in treatment?

1. To increase hemoglobin levels

2. To neutralize toxins in the blood

3. To raise platelet counts

4. To inhibit tumor growth

The correct answer is: To raise platelet counts

The main purpose of using peptibody proteins in treatment is to inhibit tumor growth. Peptibodies are engineered proteins that combine elements of peptides and antibodies, which can selectively target tumor cells or the tumor microenvironment. This targeted approach enhances the body's ability to mount an immune response against cancer cells, leading to the inhibition of their proliferation and spread. While other options such as increasing hemoglobin levels, neutralizing toxins, and raising platelet counts are relevant in various treatments, they do not align with the primary function of peptibody proteins. The specificity of peptibody proteins for tumor cells makes them particularly valuable in oncology, distinguishing them from treatments aimed at correcting blood component issues or detoxification pathways.
