TASK 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".
PROBLEM: Paragraph: Several human monoclonal antibodies (hmAbs) including b12, 2G12, and 2F5 exhibit relatively potent and broad HIV-1-neutralizing activity. However, their elicitation in vivo by vaccine immunogens based on the HIV-1 envelope glycoprotein (Env) has not been successful. We have hypothesized that HIV-1 has evolved a strategy to reduce or eliminate the immunogenicity of the highly conserved epitopes of such antibodies by using ''holes" (absence or very weak binding to these epitopes of germline antibodies that is not sufficient to initiate and/or maintain an efficient immune response) in the human germline B cell receptor (BCR) repertoire. To begin to test this hypothesis we have designed germline-like antibodies corresponding most closely to b12, 2G12, and 2F5 as well as to X5, m44, and m46 which are cross-reactive but with relatively modest neutralizing activity as natively occurring antibodies due to size and/or other effects. The germline-like X5, m44, and m46 bound with relatively high affinity to all tested Envs. In contrast, germline-like b12, 2G12, and 2F5 lacked measurable binding to Envs in an ELISA assay although the corresponding mature antibodies did. These results provide initial evidence that Env structures containing conserved vulnerable epitopes may not initiate humoral responses by binding to germline antibodies. Even if such responses are initiated by very weak binding undetectable in our assay it is likely that they will be outcompeted by responses to structures containing the epitopes of X5, m44, m46, and other antibodies that bind germline BCRs with much higher affinity/avidity. This hypothesis, if further supported by data, could contribute to our understanding of how HIV-1 evades immune responses and offer new concepts for design of effective vaccine immunogens.

SOLUTION: False

PROBLEM: Paragraph: Marine sponges and their associated bacteria have been proven to be a rich source of novel secondary metabolites with therapeutic usefulness in cancer, infection, and autoimmunity. In this study, 79 strains belonging to 20 genera of the order Actinomycetales and seven strains belonging to two genera of the order Sphingomonadales were cultivated from 18 different Caribbean sponges and identified by 16S rRNA gene sequencing. Seven of these strains are likely to represent novel species. Crude extracts from selected strains were found to exhibit protease inhibition against cathepsins B and L, rhodesain, and falcipain-2 as well as immunomodulatory activities such as induction of cytokine release by human peripheral blood mononuclear cells. These results highlight the significance of marine sponge-associated bacteria to produce bioactive secondary metabolites with therapeutic potential in the treatment of infectious diseases and disorders of the immune system.

PROBLEM: Paragraph: Monoclonal antibodies (MAbs) directed against herpes simplex virus (HSV)-coded glycoproteins gB, gC, gD and gE were employed in an in vitro model of neuroinvasiveness using sensory neurons from rat dorsal root ganglion (DRG) cells . The neurons were cultured in a two-chamber system allowing infection via the neuritic extensions exclusively . The effects of 30 MAbs on viral replication of the encephalitis-derived HSV-1 strain 2762 and its less neuroinvasive variant 2762p11 were assayed in this model . One MAb reactive with gD gave a nine-fold reduction of the virus yields of both strains . One MAb directed against gB gave an enhanced virus yield of strain 2762, but not of the 2762p11 variant . Another gB-reactive MAb decreased the virus yield of strain 2762pll, but not of 2762 after neuritic infection . The findings indicate that an alteration of gB has occurred during the passage of the strain 2762 . Mutants of the same strain were derived by infecting hybridomas producing MAb reactive with gB, gC, gD and gE, respectively . The gB hybridoma mutant showed a significantly lower neuroinvasiveness in the DRG model, and was non-virulent after snout infection of mice . We suggest that the structure of gB of the strain 2762 is of importance for the neuroinvasiveness of this strain .
