Definition: 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".
Input: Paragraph: New World (NW) hemorrhagic fever arenaviruses are rodent-borne agents that cause severe human disease. The GP1 subunit of the surface glycoprotein (GP) mediates cell attachment through transferrin receptor 1 (TfR1). We report the structure of Machupo virus (MACV) GP1 bound with human TfR1. Atomic details of the GP1:TfR1 interface clarify the importance of TfR1 residues implicated in NW arenavirus host specificity. Analysis of sequence variation among NW arenavirus GP1s and their host-species receptors in light of the molecular structure indicates determinants of viral zoonotic transmission. Infectivities of pseudoviruses in cells expressing mutated TfR1 confirm that contacts at the tip of the TfR1 apical domain determine the capacity of human TfR1 to mediate infection by particular NW arenaviruses. We propose that NW arenaviruses pathogenic to humans fortuitously acquired affinity for human TfR1 during adaptation to TfR1 of their natural hosts.
