The Paediatric BCG Vaccine Century: From Historical Success to Future Innovations

Acta Paediatrica, EarlyView.
ABSTRACT Aim The tuberculosis (TB) vaccine, Bacille‐Calmette‐Guérin (BCG), protects infants against severe forms of primary TB. Yet, it does not protect against pulmonary reactivation TB in adults. Methods A literature review was conducted between 1st January and 28th February 2025 using PubMed, Google Scholar and reports of the World Health ...

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

The FEBS Journal, EarlyView.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

MYCOBACTERIUM COMPLEX IDENTIFICATION BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

Journal of Research in Medical Sciences, 2001
Introduction: There are different ways for identification of Mycobacteria. One of the most sensitive method is HPLC of phenacyl esters of mycolic acids of Mycobacteria for rapid identification of them after their primary cultures.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization

The FEBS Journal, EarlyView.
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Retrospective study of 668 cultures for mycobacteria in a reference hospital for AIDS in Southern Brazil

Brazilian Journal of Infectious Diseases, 2003
Although AIDS patients in other countries are frequently diagnosed as having atypical mycobacterial infection, in Southern Brazil there is a clinical impression that Mycobacterium tuberculosis is the rule rather than the exception.

Can Artificial Intelligence Be Utilised to Develop Point‐of‐Care Endodontic Microbiological Technologies?

International Endodontic Journal, EarlyView.
ABSTRACT Background Primary or persistent endodontic disease is caused by microbial biofilms that irritate the pulp and periapical tissues. Extensive microbiological analyses of these biofilms and their constituent pathogens have revealed their diversity and complexity.

4‐1BB Expression and Signaling Regulates MAIT Cell Activation and Effector Functions

Immunology &Cell Biology, EarlyView.
4‐1BB is a highly expressed TNFRSF co‐stimulatory receptor on MAIT cells upon activation. Expression and signaling via 4‐1BB enhance activation and provide co‐stimulation, boosting MAIT cell effector responses to TCR‐mediated activation. ABSTRACT Mucosal associated invariant T (MAIT) cells are abundant unconventional T cells that recognize microbe ...

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.
