Results obtained showed that infection with HCMV prevented the death of THP-1 cells treated with DOX in both active and latent forms of infection. In the presence of mTOR inhibitors (rapamycin and Torin2), the sensitivity of the infected cells to DOX was restored. Rapamycin inhibited the expression of the HCMV protein IE1-p72 and increased sensitivity to DOX. Molecular targets for the creation of new drugs for the treatment of leukemia in patients infected with HCMV were determined.

Multi-drug-resistant Mycobacterium tuberculosis is an escalating global health problem, and a strong pipeline of novel compounds is needed to combat rising antimicrobial resistance. Ecumicin is a novel analogue of the natural antimycobacterial cyclic peptide ecumicin, with selective activity against Mycobacterium species. The activity of ecumicin∗ was compared to that of frontline tuberculosis therapies under in vitro conditions representative of niches where M.

Emerging evidence suggests that fusion of cancer cells with leucocytes, such as macrophages, plays a significant role in cancer metastasis and results in tumor hybrid cells that acquire resistance to chemo- and radiation therapy. However, the precise mechanisms behind the leukocyte-cancer cell fusion remain unclear. The present in vitro study explores the presence of fusion between the monocyte cell line (THP-1) and the breast cancer cell line (MCF-7) in relation to the expression of CD36 and phosphatidylserine with and without treatment of these cells with ionizing radiation.

Mycobacterium avium complex bacteria cause chronic pulmonary disease (MAC-PD) in susceptible patients [1]. The recommended treatment regimen (rifampicin, ethambutol and azithromycin) achieves 65% cure rates but with considerable toxicity and drug-drug interactions [2,3]. Minocycline proved active in monotherapy experiments using the hollow-fibre model [4].

Unlabelled: Visceral leishmaniasis (VL), caused by , remains challenging to treat due to severe side effects and increasing drug resistance associated with current chemotherapies. Our study investigates the anti-leishmanial potential of from Uttarakhand, India, with extracts prepared from leaves and stems using ethanol and hexane. Advanced GC-MS analysis identified over 100 bioactive compounds, which were screened using molecular docking to assess their binding to LdHEL-67, a DDX3-DEAD box RNA helicase of donovani.
