Skin Barrier Function: The Interplay of Physical, Chemical, and Immunologic Properties

open access: yesCells, 2023
An intact barrier function of the skin is important in maintaining skin health. The regulation of the skin barrier depends on a multitude of molecular and immunological signaling pathways.

Advances in Immunotherapy for the Treatment of Adult Glioblastoma: Overcoming Chemical and Physical Barriers

open access: yesCancers, 2022
Glioblastoma, or glioblastoma multiforme (GBM, WHO Grade IV), is a highly aggressive adult glioma. Despite extensive efforts to improve treatment, the current standard-of-care (SOC) regimen, which consists of maximal resection, radiotherapy, and temozolomide (TMZ), achieves only a 12–15 month survival.

Research advances in the structure, function, and regulation of the gill barrier in teleost fish

open access: yesWater Biology and Security, 2023
The gill is an important organ in fish that is involved in various physiological functions, including respiration, filter-feeding, ammonia nitrogen excretion, and osmoregulation. The physiological functions of gills are closely related to their structure,

Physical and Chemical Barriers in the Larval Midgut Confer Developmental Resistance to Virus Infection in Drosophila [PDF]

open access: yesViruses, 2021
Insects can become lethally infected by the oral intake of a number of insect-specific viruses. Virus infection commonly occurs in larvae, given their active feeding behaviour; however, older larvae often become resistant to oral viral infections. To investigate mechanisms that contribute to resistance throughout the larval development, we orally ...

The Compromised Intestinal Barrier Induced by Mycotoxins

open access: yesToxins, 2020
Mycotoxins are fungal metabolites that occur in human foods and animal feeds, potentially threatening human and animal health. The intestine is considered as the first barrier against these external contaminants, and it consists of interconnected ...
