Abstract
Microglia play a pivotal role in the central nervous system (CNS) homeostasis, acting as housekeepers and defenders of the surrounding environment. These cells can elicit their functions by shifting into two main phenotypes: pro-inflammatory classical phenotype, M1, and anti-inflammatory alternative phenotype, M2. Despite their pivotal role in CNS homeostasis, microglia phenotypes can influence the development and progression of several CNS disorders such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, ischemic stroke, traumatic brain injuries, and even brain cancer. It is thus clear that the possibility of modulating microglia activation has gained attention as a therapeutic tool against many CNS pathologies. Nanomaterials are an unprecedented tool for manipulating microglia responses, in particular, to specifically target microglia and elicit an in situ immunomodulation activity. This review focuses the discussion on two main aspects: analyzing the possibility of using nanomaterials to stimulate a pro-inflammatory response of microglia against brain cancer and introducing nanostructures able to foster an anti-inflammatory response for treating neurodegenerative disorders. The final aim is to stimulate the analysis of the development of new microglia nano-immunomodulators, paving the way for innovative and effective therapeutic approaches for the treatment of CNS disorders.

Abstract
The objective of this study was to develop zein-casein-lysine nanoparticles to modulate the intestinal permeability of ferulic acid (FA), a bioactive compound with proven antioxidant properties. The nanoparticles were obtained by a liquid-liquid dispersion method and were characterized in terms of mean size, polydispersity index, zeta potential, association efficiency (AE), in vitro drug release, x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The in vitro intestinal permeability of nanoparticles was evaluated through Caco-2 and Caco-2/HT29-MTX monoculture and co-culture models, respectively. Nanoparticles presented a mean size of 199 nm and zeta potential of -26 mV. The AE of FA was 23% evaluated by high-performance liquid chromatography (HPLC). XRD showed amorphization of FA after association and FT-IR showed no changes in chemical structures of the compounds after nanoencapsulation. The cytotoxicity assays demonstrated that multicomposite nanoparticles presented a safe profile against Caco-2 and HT29-MTX cells. In the in vitro permeability assay, free FA exhibited higher permeability compared to FA-loaded nanoparticles, possibly due to prolonged FA release from nanoparticles. These new developed zein-casein-lysine nanoparticles may be used for FA sustained delivery by the oral route.

Abstract
The potential of sustaining release of very small (Mw < 250 g/mol) hydrophilic drugs up to several days from layer-by-layer (LbL) polyelectrolyte coated alginate microgels (Alg-Ms) was investigated. One purpose is to minimize post-surgical adhesions, which develop in 12 h to 3 days after surgery. The LbL polyelectrolyte layer would serve as a diffusion barrier for their release. The LbL polyelectrolyte bilayers were prepared using poly(allylamine) (PAH) and poly(styrene sulfonate) (PSS). Sodium benzoate (NaB, Mw = 144 g/mol) and zosteric acid (ZA, Mw = 244 g/mol), two anti-inflammatory and anti-microbial compounds, were used as model drugs. A higher number of PAH/PSS bilayer lead to a greater sustained release of both drugs, and with 4 bilayers, the release of NaB and ZA was prolonged from 24 h to 72 h and 120 h, respectively. Fitting the data to the Ritger-Peppas' equation showed that as the bilayer number increased, the release constant and/or exponent decreased, indicating the LbL PAH/PSS bilayer effectively reduced the permeability of these two very small hydrophilic drugs. The ability to prolong the release of such small hydrophilic molecules, which has rarely been investigated previously, would find broad applications in fields such as anti-adhesion treatment and antifouling coatings.

Abstract
Crosslinked enzyme aggregates comprise more stable and highly concentrated enzymatic preparations of current biotechnological and biomedical relevance. This work reports the development of crosslinked nanosized papain aggregates using electron beam irradiation as an alternative route for controlled enzyme crosslinking. The nanoparticles were synthesized in phosphate buffer using various ethanol concentrations and electron beam irradiation doses. Particle size increase was monitored using dynamic light scattering. The crosslinking formation by means of bityrosine linkages were measured by fluorescence spectra and the enzymatic activity was monitored using Na-Benzoyl-dl-arginine p-nitroanilide hydrochloride as a substrate. The process led to crosslinked papain nanoparticles with controlled sizes ranging from 6 to 11nm depending upon the dose and ethanol concentration. The irradiation atmosphere played an important role in the final bioactivity of the nanoparticles, whereas argon and nitrous oxide saturated systems were more effective than at atmospheric conditions in terms of preserving papain enzymatic activity. Highlighted advantages of the technique include the lack of monomers and crosslinking agents, quick processing with reduced bioactivity changes, and the possibility to be performed inside the final package simultaneously with sterilization.

Abstract
The ability to efficiently deliver a drug or gene to a tumor site is dependent on a wide range of factors including circulation time, interactions with the mononuclear phagocyte system, extravasation from circulation at the tumor site, targeting strategy, release from the delivery vehicle, and uptake in cancer cells. Nanotechnology provides the possibility of creating delivery systems where the design constraints are decoupled, allowing new approaches for reducing the unwanted side effects of systemic delivery, increasing tumor accumulation, and improving efficacy. The physico-chemical properties of nanoparticle-based delivery platforms introduce additional complexity associated with pharmacokinetics, tumor accumulation, and biodistribution. To assess the impact of nanoparticle-based delivery systems, we first review the design strategies and pharmacokinetics of FDA-approved nanomedicines. Next we review nanomedicines under development, summarizing the range of nanoparticle platforms, strategies for targeting, and pharmacokinetics. We show how the lack of uniformity in preclinical trials prevents systematic comparison and hence limits advances in the field.

Abstract
A microparticulate protein delivery system was developed using collagen, from the medusa Catostylus tagi, as a polymeric matrix. Collagen microparticles (CMPs) were produced by an emulsification-gelation-solvent extraction method and a high loading efficiency was found for the entrapment of lysozyme and α-lactalbumin. CMPs were cross-linked with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC). The uncross-linked CMPs were spherical, rough-surfaced, presenting an estimated median size of 28 µm by laser diffraction. Upon cross-linking, particle size (9.5 µm) and size distribution were reduced. CMPs showed a moderate hydrophobic behaviour and a positive surface charge. Cross-linking also resulted in greater stability in water, allowing a slow release, as shown by in vitro experiments. The assessment of lysozyme's biological activity showed that the protein remained active throughout the encapsulation and cross-linking processes. In summary, the work herein described shows the potential use of a marine collagen in the production of microparticles for the controlled release of therapeutic proteins.

Abstract
This paper develops a model of nanoparticle transport in neurons. It is assumed that nanoparticles are transported inside endocytic vesicles by a combined effect of dynein-driven transport and diffusion. It is further assumed that in axons nanoparticles are internalised only at axon terminals, whereas in dendrites nanoparticles can enter through the entire plasma membrane. This causes differences in transport of nanoparticles in axons and dendrites; these differences are investigated in this paper. Another difference is microtubule (MT) orientation in axons and dendrites; in axons, all MTs have their plus-ends oriented towards the axon terminal; in a proximal region of a dendrite, MTs have mixed orientation, whereas in a distal dendritic region the MT orientation is similar to that in an axon. It is shown that if molecular-motor-driven transport were powered by dynein alone, such MT orientation in a dendrite would result in a region of nanoparticle accumulation located at the border between the proximal and distal dendritic regions.
