Detailed Instructions: In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".
Q: Paragraph: CD8 + cytotoxic T cell (CTL) responses are necessary for the lysis of virally infected cells and control of infection. CTLs are activated when their TCRs bind a major histocompatibility complex (MHC)-I/peptide complex on the surface of antigen presenting cells such as macrophages (M). It is now apparent that M display remarkable plasticity in response to environmental signals to polarize into classically activated M(LPS + IFN-) or alternatively activated M(IL-4). However, little is known about how M activation status influences their antigen presentation function to CD8 + T cell in models of virus infection. Consequently, we tested how polarization of spleen-derived (Sp)-M impacts direct presentation of viral antigens to influence effector and proliferative CD8 + T-cell responses. We show that M(IL-4) Sp-M retain MHC-I surface expression and the ability to stimulate IFN- production by CTL following peptide stimulation and lymphocytic choriomeningitis virus infection to levels similar to M0 and M(LPS + IFN-) M. However, memory CD8 + T cells cultured in the presence of M(IL-4) M underwent significantly reduced proliferation and produced similar IFN- levels as coculturing with M0 or M(LPS + IFN-) cells. Thus, these results show a novel ability of polarized M to regulate CD8 + T-cell proliferation and effector functions during virus infection.
