In recent years, the scientific community's interest in as an insect model to investigate immunity and host-pathogen interactions has considerably increased. The reasons for this growing interest could be explained by the peculiar features of this beetle, which offers various advantages compared to other invertebrates models commonly used in laboratory studies. Thus, this review aimed at providing a broad view of the immune system in light of the new scientific evidence on the developmental/tissue-specific gene expression studies related to microbial infection.

The new invasive mosquito species as vector-borne diseases in the European area, a focus on Italian region: What we know from the scientific literature.

The increased mobility of goods, people, and animals worldwide has caused the spread of several arthropod vectors, leading to an increased risk of animal and human infections. is a common species in South Korea, China, Japan, and Russia. Due to its cold-resistant dormant eggs, the adults last from the late summer until the autumn seasons.

LimpiAD foam and the potential control of the pressure ulcers onset.

Pressure ulcers development is an undesirable event that often worsens the clinical condition of patients already affected by severe pathologies. Since the aetiology of this clinical complication is unclear yet, at current the primary approach to treat the problem is the adoption of suitable patients' assistance procedures. At the same time, the research focuses on finding medicaments or treatment strategies that could prevent the lesions and/or accelerate their healing.

Potential Mucosal Irritation Discrimination of Surface Disinfectants Employed against SARS-CoV-2 by Slug Mucosal Irritation Assay.

Preventive measures have proven to be the most effective strategy to counteract the spread of the SARS-CoV-2 virus. Among these, disinfection is strongly suggested by international health organizations' official guidelines. As a consequence, the increase of disinfectants handling is going to expose people to the risk of eyes, mouth, nose, and mucous membranes accidental irritation.

The Lepidoptera Galleria mellonella "in vivo" model: a preliminary pilot study on oral administration of Lactobacillus plantarum (now Lactiplantibacillus plantarum).

This work aims to assess the in vitro adhesion of two type strains of Lactobacillus plantarum (ATCC 14917 and ATCC BAA-793) (now Lactiplantibacillus plantarum). The experiments were conducted both in vitro on colon cells lines (Caco-2 and HT-29) and in vivo by adopting Galleria mellonella, a well-known alternative preclinical model. Data comparison obtained from in vitro and in vivo assays showed that adhesion performance is comparable in both models.

Atopic Dermatitis as a Multifactorial Skin Disorder. Can the Analysis of Pathophysiological Targets Represent the Winning Therapeutic Strategy?

Atopic dermatitis (AD) is a pathological skin condition with complex aetiological mechanisms that are difficult to fully understand. Scientific evidence suggests that of all the causes, the impairment of the skin barrier and cutaneous dysbiosis together with immunological dysfunction can be considered as the two main factors involved in this pathological skin condition. The loss of the skin barrier function is often linked to dysbiosis and immunological dysfunction, with an imbalance in the ratio between the pathogen and/or other microorganisms residing in the skin.

In Vitro and In Vivo Biological Activity of Berberine Chloride against Uropathogenic Strains Using as a Host Model.
