Neurogenic inflammation and itch in barrier tissues.

Once regarded as distinct systems, the nervous system and the immune system are now recognized for their complex interactions within the barrier tissues. The neuroimmune circuitry comprises a dual-network system that detects external and internal disturbances, providing critical information to tailor a context-specific response to various threats to tissue integrity, such as wounding or exposure to noxious and harmful stimuli like pathogens, toxins, or allergens. Using the skin as an example of a barrier tissue with the polarized sensory neuronal responses of itch and pain, we explore the molecular pathways driving neuronal activation and the effects of this activation on the immune response.

Immunology in corneal transplantation-From homeostasis to graft rejection.

Immunology depends on maintaining a delicate balance within the human body, and disruptions can result in conditions such as autoimmune diseases, immunodeficiencies, and hypersensitivity reactions. This balance is especially crucial in transplantation immunology, where one of the primary challenges is preventing graft rejection. Such rejection can lead to organ failure, increased patient mortality, and higher healthcare costs due to the limited availability of donor tissues relative to patient needs.

Deciphering the colostral-immunity transfer: from mammary gland to neonates small intestine.

Colostrum, the initial mammary secretion produced by various mammals following birth, is a conduit for maternal immunity transfer in diverse mammalian species. Concurrently, many cellular processes are occurring in the neonatal small intestine to prepare it to receive molecular signals from a superfood essential for the neonate's health and development. During the prepartum colostrum secretion, the newborn intestine undergoes transient alterations in the intestinal barrier, primarily regulating immunoglobulin absorption.
