Lactic Acid Bacteria against Mycotoxins
Mycotoxins (aflatoxin, ochratoxin, patulin, zearalenone, fumonisins, trichothecenes) are a large group of chemically diverse, non-protein, low-molecular secondary metabolites produced by molds. They constitute a global threat to human food and health. The generally regarded as safe (GRAS) status and long history as essential ingredients of fermented foods and probiotics make Lactic Acid Bacteria (LAB) a major biological tool against various food-related toxins. Numerous studies have shown LAB to be effective against all major mycotoxins.

TGF-β Signaling in Tumor Microenvironment
Transforming growth factor-β (TGF-β) signaling triggers diverse biological actions in inflammatory diseases. In tissue fibrosis, it acts as a key pathogenic regulator for promoting immunoregulation via controlling the activation, proliferation, and apoptosis of immunocytes. In cancer, it plays a critical role in tumor microenvironment (TME) for accelerating invasion, metastasis, angiogenesis, and immunosuppression. Increasing evidence suggest a pleiotropic nature of TGF-β signaling as a critical pathway for generating fibrotic TME, which contains numerous cancer-associated fibroblasts, extracellular matrix proteins, and remodeling enzymes. Better understanding the underlying mechanisms may uncover novel therapeutic targets for cancer.

Isolation and Purification of EVs
Extracellular vesicles are sacs that are secreted by almost all types of cells and are responsible for intracellular communication. They inherit their content and characteristics from their donor cells. Pathological and physiological characteristics of donor cells are reflected in the appearance of specific nucleotide and proteins (on the EV surface or in their content).

Hepatitis E Genome Organization
Hepatitis E virus (HEV), a pathogen that causes acute viral hepatitis, is a small icosahedral, quasi-enveloped, positive ssRNA virus. Its genome has three open reading frames (ORFs), with ORF1 and ORF3 encoding for nonstructural and regulatory proteins, respectively, while ORF2 is translated into the structural, capsid protein. ORF2 is most widely used for vaccine development in viral hepatitis. Hepatitis E virus-like particles (VLPs) are potential vaccine candidates against HEV infection. VLPs are composed of capsid subunits mimicking the natural configuration of the native virus but lack the genetic material needed for replication. As a result, VLPs are unable to replicate and cause disease, constituting safe vaccine platforms. Currently, the recombinant VLP-based vaccine Hecolin® against HEV is only licensed in China.

Brain Microvascular Pericytes in Breast Cancer Brain Metastasis
Brain tissue contains the highest number of perivascular pericytes compared to other organs. Pericytes are known to regulate brain perfusion and to play an important role within the neurovascular unit (NVU). The high phenotypic and functional plasticity of pericytes make this cell type a prime candidate to aid physiological adaptations but also propose pericytes as important modulators in diverse pathologies in the brain. This research highlights known phenotypes of pericytes in the brain, discusses the diverse markers for brain pericytes, and reviews current in-vitro and in-vivo experimental models to study pericyte function.

Toxoplasma gondii-Induced and Associated Diseases
Toxoplasma gondii (T. gondii) is a prevalent protozoan parasite of medical and veterinary significance. It is the etiologic agent of toxoplasmosis, a neglected disease in which incidence and symptoms differ between patients and regions. In immunocompetent patients, toxoplasmosis manifests as acute and chronic forms. Acute toxoplasmosis presents as mild or asymptomatic disease that evolves, under the host immune response, into a persistent chronic disease in healthy individuals. Chronic toxoplasmosis establishes as latent tissue cysts in the brain and skeletal muscles. In immunocompromised patients, chronic toxoplasmosis may reactivate, leading to a potentially life-threatening condition.

Protein Glycosylation
Protein glycosylation is a highly conserved post-translational modification among organisms. It plays fundamental roles in many biological processes, ranging from protein trafficking and cell adhesion to host–pathogen interactions. According to the amino acid side chain atoms to which glycans are linked, protein glycosylation can be divided into two major categories: N-glycosylation and O-glycosylation. However, there are other types of modifications such as the addition of GPI to the C-terminal end of the protein. Besides the importance of glycoproteins in biological functions, they are a major component of the fungal cell wall and plasma membrane and contribute to pathogenicity, virulence, and recognition by the host immunity. Given that this structure is absent in host mammalian cells, it stands as an attractive target for developing selective compounds for the treatment of fungal infections.

Non-Spiking Neuron
Non-spiking neurons are neurons that are located in the central and peripheral nervous systems and function as intermediary relays for sensory-motor neurons. They do not exhibit the characteristic spiking behavior of action potential generating neurons. Non-spiking neural networks are integrated with spiking neural networks to have a synergistic effect in being able to stimulate some sensory or motor response while also being able to modulate the response.
