Nanovaccines for remodeling the suppressive tumor microenvironment: New horizons in cancer immunotherapy

Kai Shi, Matthew Haynes, Leaf Huang

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 4,   Pages 676-684 doi: 10.1007/s11705-017-1640-4

Abstract: Despite limited successes in clinical development, therapeutic cancer vaccines have experienced resurgence in recent years due to an enhanced emphasis upon co-mitigating factors underlying immune response. Specifically, reversing the immune-suppressive effects of the tumor microenvironment, mediated by a variety of cellular and molecular signaling mechanisms, has become fundamental toward enhancing therapeutic efficacy. Therein, our lab has implemented various nano-vaccines based on the lipid-coated calcium phosphate platform for combined immunotherapy, in which antigenic, epitope-associated peptides as well as immune-suppression inhibitors can be co-delivered, often functioning through the same formulation. In probing the mechanism of action of such systems and , an improved effect synergy can be elucidated, inspiring future preclinical efforts and hope for clinical success.

Computation of the protein molecular mechanism using adaptive dihedral angle increments

Mikel DIEZ, Victor PETUYA, Mónica URIZAR, Erik MACHO, Oscar ALTUZARRRA

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 1,   Pages 104-108 doi: 10.1007/s11465-013-0360-9

Abstract:

Protein motion simulation is still a troublesome problem yet to be solved, especially due to its high computational requirements. The procedure presented in this paper makes use of the proteins’ real degrees of freedom (DOFs). The procedure makes no use of any intermediate energy minimization processes that may alter the motion path or result in very high computational cost requirements. In order to reduce the computational cost, presented algorithms make use of the balls and rods approach for protein structure modelization. Also, structures are normalized in order to minimize inaccuracies introduced by experimental methods, providing a more efficient but still accurate structure for motion simulation.
