Differentiation of bone marrow eosinophils (BM-EO) and its trafficking to peripheral blood and respiratory mucosa are a hallmark of inflammatory diseases. Staphylococcal enterotoxin B (SEB) has been shown to aggravate airways eosinophilic inflammation. This study aimed to investigate the effects of mouse airways SEB exposure on BM-EO population, as well as its adhesive properties and release of cytokines/chemokines that orchestrate BM-EO trafficking to lungs.

Male BALB/c mice were intranasally exposed to SEB (1μg), and at 4, 16, 24 and 48h thereafter, bone marrow (BM), circulating blood and bronchoalveolar lavage (BAL) fluid were collected. Levels of cytokines/chemokines and expressions of VLA-4 and CCR3 in BM were evaluated. Adhesion of BM to ICAM-1 and VCAM-1 were also evaluated.

SEB exposure promoted a marked eosinophil influx to BAL at 16 and 24h after exposure, which was accompanied by significant increases in counts of immature (16h) and mature (4 to 48h) forms of eosinophil in BM, along with blood eosinophilia (16h). In BM, higher levels of eotaxin, IL-5, IL-4, IL-3 and IL-7 were detected at 16 to 48h. SEB also significantly increased CCR3 expression and calcium levels in BM-EO, and enhanced the cell adhesion to ICAM-1 (24h) and ICAM-1 (48h).

Airways SEB exposure increases the number of eosinophils in BM by mechanisms involving a network of cytokine and chemokine release, facilitating the BM-EO adhesion to ICAM-1 and VCAM-1 to gain access to the peripheral blood and lung tissues.

It has been shown that the infiltration of neutrophils, either by exerting pro- or anti-tumoral effects, probably affects tumor prognosis. Tumor-associated neutrophils (TANs) probably participate in tumor promotion and development in different ways, such as increasing genomic instability, induction of immunosuppression, and increasing angiogenesis. Despite major advances in breast cancer treatment, it is the second leading cause of death in American women. It has been revealed that inflammation is a fundamental issue in the treatment of this cancer because tumor growth, invasion, metastasis, and vascularization can be affected by inflammatory factors. It is demonstrated that enhanced neutrophil to lymphocyte ratio probably contributes to the raised rate of mortality and decreased survival among breast cancer cases. The present review explores the biology of TANs, their suspected interactions in the breast cancer microenvironment, and their functions in preserving the tumor microenvironment and progression of tumors. Furthermore, their potential as therapeutic targets and clinical biomarkers has been discussed in this paper.Fluorescence is routinely used for in vivo tracking and imaging of molecules and nanostructures with assuming that the fluorescence intensity is proportional to the dye concentration. Herein, we report the unique tumor-specific fluorescence character of rhodamine B isothiocyanate derivatives (RBITCs), which emits fluorescence selectively in cancerous tissues, including small metastatic tumors, but is quenched in blood and healthy tissues. click here A preliminary mechanism study shows that binding of the thiourea group in the RBITCs on hemoglobin quenches their fluorescence, but the oxidation of the thiourea by the elevated reactive oxygen species in tumor activates the fluorescence. Thus, the fluorescent intensity of RBITCs is associated with the microenvironment of tissues and positively correlates with the cancer stages. These findings suggest that the RBITCs are not suitable for tracking of cargos in the presence of red blood cells but may be useful for cancer imaging and early diagnosis, and probing the tumor microenvironment.Owing to their tremendous potential, the inference of nano-scaled materials has revolutionized many fields including the medicine and health, particularly for development of various types of targeted drug delivery devices for early prognosis and successful treatment of various diseases, including the brain disorders. Owing to their unique characteristic features, a variety of nanomaterials (particularly, ultra-fine particles (UFPs) have shown tremendous success in achieving the prognostic and therapeutic goals for early prognosis and treatment of various brain maladies such as Alzheimer's disease, Parkinson's disease, brain lymphomas, and other ailments. However, serious attention is needful due to innumerable after-effects of the nanomaterials. Despite their immense contribution in optimizing the prognostic and therapeutic modalities, biological interaction of nanomaterials with various body tissues may produce severe nanotoxicity of different organs including the heart, liver, kidney, lungs, immune system, gastro-intestinal system, skin as well as nervous system. However, in this review, we have primarily focused on nanomaterials-induced neurotoxicity of the brain. Following their translocation into different regions of the brain, nanomaterials may induce neurotoxicity through multiple mechanisms including the oxidative stress, DNA damage, lysosomal dysfunction, inflammatory cascade, apoptosis, genotoxicity, and ultimately necrosis of neuronal cells. Our findings indicated that rigorous toxicological evaluations must be carried out prior to clinical translation of nanomaterials-based formulations to avoid serious neurotoxic complications, which may further lead to develop various neuro-degenerative disorders.Encapsulation technologies can be used to preserve therapeutic and bioactive compounds from harsh conditions (e.g., light, moisture, and oxygen) and biological destruction (enzymes, metabolism, and phagocytosis). Encapsulation involves the incorporation of the active moieties into a shell structure (e.g., protein, polysaccharide or lipid-based material). These techniques can improve the physicochemical properties of the encapsulated compounds, provide sustained release to specific organs, "cover up" undesirable properties, and improve their solubility, dispersion, and bioavailability. Different techniques have been applied to encapsulate drug compounds, including emulsification, inclusion complexation, nanoparticulate systems (solid lipid nanoparticles and nanostructured lipid carriers), liposome entrapment, nanoprecipitation, freeze drying, spray drying, etc. However, high temperatures or toxic solvents are used in some of these techniques such as spray drying, and liposome entrapment can degrade the bioactive compounds or reduce their functionality.
