Introduction: Tuberculosis (TB) is a significant cause of morbidity worldwide, especially in the low and middle-income countries like India and is found to be more common in the rural areas. Delays in diagnosis and initiation of treatment along with lower treatment adherence and completion rates have increased the morbidity and mortality of TB in the rural areas. The collation of information accumulated through the assessment of people's Knowledge, Attitude, and Practices (KAP) towards TB, helps in charting new health programs for the public, identifying lacunae, and devising interventions based on these lacunae which in turn will help us to achieve the vision of a "TB free India” by 2025. Aim: To find out KAP and any association amongst them regarding TB among the study subjects. Materials and Methods: This was a cross-sectional study conducted on patients attending Outpatient Department (OPD) at the Rural Health Training Centre (RHTC) attached to NCR Institute of Medical Sciences, Meerut, Uttar Pradesh, India, during January 2021 to April 2021. From a sample of 106 patients data of KAP regarding TB was collected via a structured questionnaire which was predesigned and pretested. Pearson’s Chi-square test was used to ascertain the association between subjects' KAP about TB. A p-value <0.05 was taken as the predictor of statistical significance. Results: Out of 106 patients, 72 (67.92%), 80 (75.47%) and 52 (49.06%) had adequate KAP respectively. Participants having adequate knowledge showed positive attitude and good practices and this association was found to be statistically significant. Conclusion: The study results reflect that having adequate knowledge of the disease transforms into good practices and a positive attitude towards a person suffering from the said disease as well as helps the people to have a positive frame of mind in case they themselves contract the disease. Health education and behaviour change communication hence needs to be scaled up in rural communities to prevent, detect and treat tuberculosis in order to achieve a TB free India.

With rising incidence of acquired drug resistance among life-threatening pathogens, alternative approaches to improve therapy and vaccination have taken center stage. To this end, genome-wide and pathway-specific siRNA libraries are being employed increasingly to identify genes that regulate immune responses against a number of pathogens. In this study using calcium and cysteine protease pathway-specific siRNA libraries, we identified genes that play critical roles in modulating diverse functions of dendritic cells (DCs) during Mycobacterium tuberculosis infection. Knockdown of many of these genes in the two pathways resulted in reduced bacterial burden within DCs. These included genes that regulated activation of transcription factors, ubiquitin-specific peptidases, and genes that are involved in autophagy and neddylation. Knockdown of certain genes increased the expression of IL-12p40 and surface densities of costimulatory molecules in an antigen- and receptor-specific manner. Increased IL-12p40 and costimulatory molecules on DCs also promoted the development of Th1 responses from a Th2 inducing antigen. Furthermore, modulation of autophagy and oxidative burst appeared to be one of the mechanisms by which these genes regulated survival of M. tuberculosis within DCs. Although some genes regulated specific responses, others regulated multiple responses that included IL-12 production, T cell priming, as well as intracellular survival of M. tuberculosis. Further dissection of the mechanisms such as neddylation, by which these genes regulate immune responses, would improve our understanding of host parameters that are modulated during M. tuberculosis infection.
