Host-directed therapies for malaria and tuberculosis: common infection strategies and repurposed drugs.

Introduction: Malaria and tuberculosis are highly infectious diseases declared a global health emergency by the World Health Organization, and together they account for more than 1.5 million deaths worldwide each year. In the case of both malaria and tuberculosis, emergence of multidrug resistance towards frontline drugs has been reported in the recent past.

Comparative Outcomes of Second-line Topoisomerase-I Inhibitor Therapies on Neuroendocrine Carcinoma.

Introduction: This investigation aims to assess the outcomes for second-line therapies to treat extrapulmonary neuroendocrine carcinoma (EP-NEC) after first-line platinum-based chemotherapy.

Methods: With IRB approval, we conducted a retrospective study of EP-NEC patients that progressed on first-line platinum chemotherapy from 2008 to 2018. Demographic data and treatment-related characteristics were collected and represented as descriptive statistics.

Host-directed therapies: a potential solution to combat COVID-19.

Coronavirus disease 2019 (COVID-19) characterized by immuno-pathological host responses including pneumonia, lymphopenia, and cytokine storm that leads to severe lung inflammation, developed in acute respiratory distress syndrome (ARDS). In the absence of an effective vaccine or any definitive cure, the use of host-directed therapies is an effective alternative and demanding treatment option in the current pandemic outbreak of COVID-19.

The role of T regulatory cell-associated markers in monitoring tuberculosis treatment completion and failure.

Monitoring tuberculosis (TB) treatment success is crucial for clinical decision-making. The only available tool in this regard is sputum microscopy, but it has demerits. Moreover, in case of smear negatives and extrapulmonary TB, an efficient tool is still sought for.

T regulatory cells: Achilles' heel of Mycobacterium tuberculosis infection?

T regulatory cells (Treg) constitute a specialized subset of T cells that play a pivotal role in preventing the occurrence of autoimmune diseases by suppressing deleterious activities of immune cells. Contrarily, they can have adverse effect on immune response against infectious diseases where Treg weaken the host immunity leading to enhanced microbial load and thereby increase in severity of the disease. Here, we have attempted to review plethora of information documenting prevalence of Treg in tuberculosis (TB) and their involvement in progression and immunopathogenesis of the disease.

Physicochemical properties of the modeled structure of astacin metalloprotease moulting enzyme NAS-36 and mapping the druggable allosteric space of Heamonchus contortus, Brugia malayi and Ceanorhabditis elegans via molecular dynamics simulation.

Nematodes represent the second largest phylum in the animal kingdom. It is the most abundant species (500,000) in the planet. It causes chronic, debilitating infections worldwide such as ascariasis, trichuriasis, hookworm, enterobiasis, strongyloidiasis, filariasis and trichinosis, among others.
