Biomaterials-based anti-inflammatory treatment strategies for Alzheimer's disease.

ABSTRACT: The current therapeutic drugs for Alzheimer's disease only improve symptoms, they do not delay disease progression. Therefore, there is an urgent need for new effective drugs. The underlying pathogenic factors of Alzheimer's disease are not clear, but neuroinflammation can link various hypotheses of Alzheimer's disease; hence, targeting neuroinflammation may be a new hope for Alzheimer's disease treatment. Inhibiting inflammation can restore neuronal function, promote neuroregeneration, reduce the pathological burden of Alzheimer's disease, and improve or even reverse symptoms of Alzheimer's disease. This review focuses on the relationship between inflammation and various pathological hypotheses of Alzheimer's disease; reports the mechanisms and characteristics of small-molecule drugs (e.g., nonsteroidal anti-inflammatory drugs, neurosteroids, and plant extracts); macromolecule drugs (e.g., peptides, proteins, and gene therapeutics); and nanocarriers (e.g., lipid-based nanoparticles, polymeric nanoparticles, nanoemulsions, and inorganic nanoparticles) in the treatment of Alzheimer's disease. The review also makes recommendations for the prospective development of anti-inflammatory strategies based on nanocarriers for the treatment of Alzheimer's disease.

Project description:Ischemic heart disease (IHD) is clinical manifestation of chronic inflammatory progressive pathological process of atherosclerosis in coronary arteries. IHD is the leading cause of morbidity and mortality in the world. The question is whether it is possible to improve and direct the therapeutic treatment of IHD patients in the treatment of the inflammatory process in the atherosclerotic leasions.A prospective, comparative, analytica,clinically applicable, open-type study was performed. The study was conducted on 80 subjects with controlled biohumoral markers: troponin, CK, CK MB, BNP; markers of atherogenesis: LDL and homocystein; inflammatory markers: CRP, amyloid, cytokines IL-2, IL-6,TNF-alpha. The experimental group of 38 respondents had in addition to the conventional IHD treatment with: ampicillin (which included organosulfur compounds), cyancobalamin, vitamin B complex (B1, B2 and B6) and folacin. A control group of 42 respondents did not have this additional treatment.Major adverse cardic events (MACE) such as postinfarctic angina pectoris and repeated infarction, need for surgical interventions of myocardial revascularization, signs of cardiac insufficiency and death were observed during the one-year period. There was no correlation between the IL-2, IL-6 and TNF-alpha, as well as CK, CKMB and troponin and MACE in one-year follow-up. There was a strong positive correlation between MACE and CRP (p = 0,0002) and amyloid (p = 0,0005) as inflamatory markers; a strong positive correlation between MACE and homocysteine as an atherogenic marker (p = 0,0002, and amoderate positive correlation between MACE and BNP (p = 0.0403) as ischemic marker and marker of cardiac insufficiency. The echocardiographically monitored systolic function showed a moderate difference in the groups with average higher values in the experimantal group (p = 0.0282).The applied treatment exhibited a moderate positive effect on the systolic function of LV and significantly reduced the MACE in the work compared to the control group (p <0.0001), and demonstrated a potential anti-inflammatory effect.

Project description:Biomaterials are now being used or evaluated clinically as implants to supplement the severe shortage of available human donor organs. To date, however, such implants have mainly been developed as scaffolds to promote the regeneration of failing organs due to old age or congenital malformations. In the real world, however, infection or immunological issues often compromise patients. For example, bacterial and viral infections can result in uncontrolled immunopathological damage and lead to organ failure. Hence, there is a need for biomaterials and implants that not only promote regeneration but also address issues that are specific to compromised patients, such as infection and inflammation. Different strategies are needed to address the regeneration of organs that have been damaged by infection or inflammation for successful clinical translation. Therefore, the real quest is for multifunctional biomaterials with combined properties that can combat infections, modulate inflammation, and promote regeneration at the same time. These strategies will necessitate the inclusion of methodologies for management of the cellular and signaling components elicited within the local microenvironment. In the development of such biomaterials, strategies range from the inclusion of materials that have intrinsic anti-inflammatory properties, such as the synthetic lipid polymer, 2-methacryloyloxyethyl phosphorylcholine (MPC), to silver nanoparticles that have antibacterial properties, to inclusion of nano- and micro-particles in biomaterials composites that deliver active drugs. In this present review, we present examples of both kinds of materials in each group along with their pros and cons. Thus, as a promising next generation strategy to aid or replace tissue/organ transplantation, an integrated smart programmable platform is needed for regenerative medicine applications to create and/or restore normal function at the cell and tissue levels. Therefore, now it is of utmost importance to develop integrative biomaterials based on multifunctional biopolymers and nanosystem for their practical and successful clinical translation.
