Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Dietary modulation of endogenous host defense peptide synthesis as an alternative approach to in-feed antibiotics

Animal Nutrition, 2018
Traditionally, antibiotics are included in animal feed at subtherapeutic levels for growth promotion and disease prevention. However, recent links between in-feed antibiotics and a rise in antibiotic-resistant pathogens have led to a ban of all ...

Antimicrobial peptide LL-37 and recombinant human mannose-binding lectin express distinct age- and pathogen-specific antimicrobial activity in human newborn cord blood in vitro [PDF]

, 2018
Background: There is a need to prevent and treat infection in newborns. One approach is administration of antimicrobial proteins and peptides (APPs) such as LL-37, a membrane-active cathelicidin antimicrobial peptide, and mannose-binding lectin (MBL), a ...

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome

Advanced Science, EarlyView.
By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

The microbiome in patients with atopic dermatitis. [PDF]

, 2019
As an interface with the environment, the skin is a complex ecosystem colonized by many microorganisms that coexist in an established balance. The cutaneous microbiome inhibits colonization with pathogens, such as Staphylococcus aureus, and is a crucial ...

A Keratinocyte‐Mast Cell NF‐κB2/CXCL2/IL‐6 Amplification Loop Enhances Cutaneous Antifungal Defense Against C. albicans

Advanced Science, EarlyView.
ABSTRACT Mast cells (MCs), key innate immune sentinels at the host–environment interface, serve as primary responders to invading pathogens. However, their specific contribution to host defense against cutaneous Candida albicans (C. albicans) infection and their synergy with other immune and non‐immune cells remain poorly understood. Here, we show that

Exploring the pharmacological potential of promiscuous host-defense peptides: from natural screenings to biotechnological applications

Frontiers in Microbiology, 2011
In the last few years, the number of bacteria with enhanced resistance to conventional antibiotics has dramatically increased. Most of such bacteria belong to regular microbial flora, becoming a real challenge, especially for immune-depressed patients ...

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

Keratinocytes from human skin respond as typical immune cells after the stimulation with _Trichophyton rubrum_ [PDF]

, 2007
_Trichophyton rubrum_ is the main agent causing dermatophytosis (1). Keratinocytes are considered to be the first physical barrier of defense against pathogens (2). But not only a physical barrier.
