Autophagy is a fundamental pillar of cellular resilience, indispensable for maintaining cellular health and vitality. It coordinates the meticulous breakdown of cytoplasmic macromolecules as a guardian of cell metabolism, genomic integrity, and survival. In the complex play of biological warfare, autophagy emerges as a firm defender, bravely confronting various pathogenic, infectious, and cancerous adversaries.

Novel vaccination strategies are crucial to efficiently control tuberculosis, as proposed by the World Health Organization under its flagship program "End TB Strategy." However, the emergence of drug-resistant strains of Mycobacterium tuberculosis (Mtb), particularly in those coinfected with HIV-AIDS, constitutes a major impediment to achieving this goal. We report here a novel vaccination strategy that involves synthesizing a formulation of an immunodominant peptide derived from the Acr1 protein of Mtb.

Article Synopsis
  • COVID-19, caused by the SARS-CoV-2 virus, continues to affect the world significantly, prompting intense research for effective treatments and the approval of several vaccines.
  • The virus's ability to mutate, leading to variants that can evade immune responses, raises concerns about the long-term effectiveness of these vaccines.
  • Researchers have identified a plant lectin, NTL-125, from Narcissus tazetta, which shows strong potential in inhibiting SARS-CoV-2 replication by binding to the virus’s spike protein, possibly serving as a promising antiviral therapy for COVID-19.

Context: Dentists across the globe are witnessing a completely unforeseen and uncertain professional situation during these times of COVID-19 pandemic. There is conflicting evidence regarding the effectiveness of routinely used mouthwashes and especially Chlorhexidine, to reduce the viral load in oral cavity and the aerosols during oral procedures.

Aims: Comparative evaluation of the effectiveness of the current 'gold standard' chlorhexidine and povidone iodine as a control agent, through an in-vitro analysis.

Background: Approximately 80% - 90% of individuals infected with latent Mycobacterium tuberculosis (Mtb) remain protected throughout their life-span. The release of unique, latent-phase antigens are known to have a protective role in the immune response against Mtb. Although the BCG vaccine has been administered for nine decades to provide immunity against Mtb, the number of TB cases continues to rise, thereby raising doubts on BCG vaccine efficacy.

The gut microbiota significantly regulates the development and function of the innate and adaptive immune system. The attribute of immunological memory has long been linked only with adaptive immunity. Recent evidence indicates that memory is also present in the innate immune cells such as monocytes/macrophages and natural killer cells.

Host-directed therapies have emerged as an innovative and promising approach in tuberculosis (TB) treatment due to the observed limitations of current TB regimen such as lengthy duration and emergence of drug resistance. Thus, we explored the role of curdlan (beta glucan polysaccharide) as a novel strategy to activate macrophages against (). The aim of the study was to investigate the role of curdlan in restricting the growth both and .
