In mice, the early host response to intravenous infection with small doses of dispersed Mycobacterium bovis BCG is controlled by the Bcg gene. After infection with a low dose of M. bovis BCG, Lyt-1+ cells were generated in the spleens of BCG-susceptible mice (Bcgs) in parallel with an increase in the proportion of phagocytic cells. Very few changes occurred in the splenic cell types of BCG-resistant mice (Bcgr).

Long-term evaluation in BALBc mice of a triple mutant of Mycobacterium bovis and the Bacillus Calmette-Guérin as potential vaccines against bovine tuberculosis.

There is currently no commercial vaccine available against bovine tuberculosis (bTB). Mycobacterium bovis is the primary causative agent of bTB and is closely related to Mycobacterium tuberculosis, the pathogen responsible for human TB. Despite their limitations, mouse models are invaluable in early vaccine development due to their genetic diversity, cost-effectiveness, and the availability of research tools.

Host Long Noncoding RNAs as Key Players in Mycobacteria-Host Interactions.

Department of Biochemistry and Molecular Biology, Oklahoma State University, Stillwater, OK 74078, USA.

Mycobacterial infections, caused by various species within the Mycobacterium genus, remain one of the main challenges to global health across the world. Understanding the complex interplay between the host and mycobacterial pathogens is essential for developing effective diagnostic and therapeutic strategies. Host long noncoding RNAs (lncRNAs) have emerged as key regulators in cellular response to bacterial infections within host cells.

Loss of the glutathione-S-transferases Theta 2 (Gstt2) expression is associated with an improved response to intravesical , Bacillus Calmette-Guérin (BCG) immunotherapy for non-muscle-invasive bladder cancer (NMIBC) patients who receive fewer BCG instillations. To delineate the cause, Gstt2 knockout (KO) and wildtype (WT) C57Bl/6J mice were implanted with tumors before treatment with BCG or saline. RNA was analyzed via single-cell RNA sequencing (scRNA-seq) and real-time polymerase chain reaction (RT-PCR).

Thermosensitive hydrogel delivery of BCG lysates and tumor antigens: A novel strategy for melanoma immunoprevention and therapeutics.

Melanoma, recognized as one of the most aggressive forms of skin cancer, continues to show a steady rise in global incidence. While Bacillus Calmette-Guérin (BCG) has been identified as a potential intralesional therapy for melanoma, its therapeutic efficacy remains suboptimal. This study introduces a novel thermosensitive hydrogel formulated with BCG lysates and either OVA peptide or tumor cell lysates (PPP-BCG-OVA/TL).
