Finally, we investigated whether cell-to-cell virus transfer was influenced by TB-associated microenvironment. Tunneling nanotube (TNT) formation has been proposed as a macrophage-to-macrophage transmission process for host and microbial material (Dupont et al., 2018, Eugenin et al., 2009, Hashimot...
Coinfection with the human immunodeficiency virus (HIV) has been an important factor in the emergence and spread of resistance.[18] (See Treatment.) Mycobacterium tuberculosis (Mtb), a tubercle bacillus, is the causative agent of TB. It belongs to a group of closely related organisms in the ...
Lymphocytes are then recruited to the infection site, initiating a cell-mediated immune response, in which a pile of immune cells arrives, attempting to sequester the bacteria and limit further multiplication [8]. At this stage, the host remains asymptomatic, and the TB bacteria may get ...
which are vital for battling the virus. Antibodies that aid in the eradication of infections are secreted by B cells that have been stimulated during the humoral response. As part of the cellular response, T lymphocytes bind epitopes on the surface of host cells which are provided by major his...
Tuberculosis is one of the oldest diseases known to humankind and it is currently a worldwide threat with 8–9 million new active disease being reported every year. Among patients with co-infection of the human immunodeficiency virus (HIV), tuberculosis is ultimately responsible for the most death...
TB disproportionately affects low- and middle-income countries, where factors such as migrant population, malnutrition, type 2 diabetes, human immunodeficiency virus (HIV) co-infection, and COVID-19 exacerbate its impact. TB also leads to substantial economic losses due to decreased productivity and ...
