J Control Release 2024; 372:482-493. [PMID: 38914205 DOI: 10.1016/j.jconrel.2024.06.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/20/2024] [Accepted: 06/21/2024] [Indexed: 06/26/2024]
Abstract
The development of high-purity antigens promotes the urgent need of novel adjuvant with the capability to trigger high levels of immune response. Polyinosinic-polycytidylic (Poly(I:C)) is a synthetic double-stranded RNA (dsRNA) that can engage Toll-like receptor 3 (TLR3) to initiate immune responses. However, the Poly(I:C)-induced toxicity and inefficient delivery prevent its applications. In our study, combination adjuvants are formulated by aluminum oxyhydroxide nanorods (AlOOH NRs) and Poly(I:C), named Al-Poly(I:C), and the covalent interaction between the two components is further demonstrated. Al-Poly(I:C) mediates enhanced humoral and cellular immune responses in three antigen models, i.e., HBsAg virus-like particles (VLPs), human papilloma virus (HPV) VLPs and varicella-zoster virus (VZV) glycoprotein E (gE). Further mechanistic studies demonstrate that the dose and molecular weight (MW) of Poly(I:C) determine the physicochemical properties and adjuvanticity of the Al-Poly(I:C) combination adjuvants. Al-Poly(I:C) with higher Poly(I:C) dose promotes antigen-bearing dendritic cells (DCs) recruitment and B cells proliferation in lymph nodes. Al-Poly(I:C) formulated with higher MW Poly(I:C) induces higher activation of helper T cells, B cells, and CTLs. This study demonstrates that Al-Poly(I:C) potentiates the humoral and cellular responses in vaccine formulations. It offers insights for adjuvant design to meet the formulation requirements in both prophylactic and therapeutic vaccines.

Abstract
Normal human skin (NB1-RGB) cells were cultured in the presenceof polyinosinic and polycytidylic acids, diethylaminoethyldextran, cycloheximide and actinomycin D, which induced humaninterferon-beta. The simplest induction method, that requiredonly polyinosinic and polycytidylic acids and diethylaminoethyldextran was found to give the highest production ofinterferon-beta by the cells. The cell growth and productionof interferon-beta were investigated for NB1-RGB cellscultured on silk fibroin, poly(gamma-methyl-L-glutamate),poly(gamma-benzyl-L-glutamate) and collagen films prepared bythe Langmuir-Blodgett (LB) and casting methods. The cell densityof NB1-RGB cells cultured on the LB films was found to be higherthan that on the cast films made of the same polymer. Thisindicates that not only the chemical structure of the polymersused for the preparation of the films but the preparationmethods of the films, i.e., casting and LB methods, are also astrong factor affecting the cell growth. The production ofinterferon-beta per unit number of cells was found to behigher on the cast films than that on the LB films made of thesame polymer. This is explained by the fact that the optimalsuppressed growth of NB1-RGB cells on the cast films leads tothe enhanced production of interferon-beta on the cast filmscompared to those on the LB films prepared by the same polymer.

Abstract
Ampligen, a mismatched double stranded RNA, is hypothesized to be an ideal base therapy for HIV disease to which other agents, such as the nucleoside analogue, AZT, can be advantageously added. The unique properties of Ampligen which support this hypothesis include activation of immune cells, inhibition of virus replication by inducing an antiviral cellular state and inhibition of growth of neoplastic cells. Ampligen is synergistic with other agents being used or being tested for use in HIV disease and is without toxicity.

Abstract
The study of double-stranded RNA (dsRNA) encompasses a variety of fields. Basic research in this area has contributed to a greater mechanistic understanding of gene induction, tumor cell growth arrest, the establishment of antiviral states, and immunomodulation. Because of the possible clinical value of these molecules, physicians are now exploring the use of synthetic dsRNA to treat patients with cancer, HIV-1 disease, and immune dysfunction. Continued studies of the mechanisms of action of dsRNA are likely to suggest an even wider scope of clinical applications.
