Novel Sarcoidosis Epitope Augments MHCII, CD80/CD86 Expression, Promotes B-Cell Differentiation and IgG Production.

Numerous chronic human disorders are associated with immune activation by obscure antigen(s). We identified a novel sarcoidosis-epitope (ChainA) by immunoscreening of a novel T7 phage library and confirmed an abundance of ChainA IgG-antibody in sarcoidosis. We tested whether ChainA epitope elicits immune responses through B-cell activation, plasma cell differentiation and antibody production.

Bronchiectasis is a well-recognized chronic respiratory disease characterized by a productive cough and multi-microbial activation syndrome (MMAS) of various respiratory infections due to what can be the permanent dilatation of the bronchi. Bronchiectasis represents an ongoing challenge to conventional antibiotic treatment as the damaged bronchial environment remains conducive to ongoing opportunistic infections and microbial mutations, leading to multi-drug resistance. Standard treatment guidelines are designed to promptly identify and address the primary infection.

Introduction: Hypervirulent carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) poses an increasing public health risk due to its high treatment difficulty and associated mortality, especially in bone marrow transplant (BMT) patients. The emergence of strains with multiple resistance mechanisms further complicates the management of these infections.

Methods: We isolated and characterized a novel ST11-KL64 hv-CRKP strain from a pediatric bone marrow transplantation patient.

Antibiotic resistance poses a significant threat to global health, making the development of alternative strategies to combat bacterial pathogens increasingly urgent. One such promising approach is the strategic use of bacteriophages (or phages) to specifically target and eradicate antibiotic-resistant bacteria. Phages, being among the most prevalent life forms on Earth, play a critical role in maintaining ecological balance by regulating bacterial communities and driving genetic diversity.

Formation of biofilms by bacteria is a major challenge in a clinical setting. The importance of these biofilms increases in specialties where foreign bodies and prosthetic material are used. Orthopaedics is such a speciality and phage therapy could offer additional therapeutic options when dealing with biofilm infections.
