    “…Scientific research on NTDs from researchers in Arab countries (a) has experienced slow growth; (b) generated a relatively inadequate number of publications over the study period; (c) was disseminated mainly through journals in the field of parasitology or tropical medicine; (d) was contributed by researchers from the 22 Arab countries, but mainly by researchers from Egypt, Saudi Arabia, and Sudan; (e) has fragmented author networks with weak collaboration between active authors in the field; (f) was characterized by strong cross-country research collaboration with researchers in the US and the UK; (g) has focused on three main diseases, specifically, schistosomiasis, leishmaniasis, and onchocerciasis, and (h) showed less emphasis on soil-transmitted helminthiasis infections despite high prevalence. …”

    “…Leishmania, an early branching eukaryote and the causative agent of leishmaniasis, has no functional NHEJ pathway due to its lack of DNA ligase IV and other NHEJ factors but retains Ku70 and Ku80 proteins. …”

    “…We studied an established murine model of moderate acute malnutrition at baseline and after acute inflammatory challenge with bacterial lipopolysaccharide (LPS), a surrogate of Gram-negative bacterial sepsis, or Leishmania donovani, the cause of visceral leishmaniasis. Both of these infections cause significant morbidity and mortality in malnourished children. …”

    “…Parasites of the genus Leishmania are unusual unicellular microorganisms in that they are characterized by the capability to subvert in their favor the immune response of mammalian phagocytes, including dendritic cells. Thus, in overt leishmaniasis, dendritic cells and macrophages are converted into a niche for Leishmania spp. in which the parasite, rather than being inactivated and disassembled, survives and replicates. …”

    “…We also demonstrate that this provirus is elevated in vivo and correlates with interferon gamma signaling activity in cutaneous leishmaniasis patients. This study provides key insights into the HML-2 subgroup and suggests that it may participate in enhancing pro-inflammatory signaling in macrophages and probably other immune cells.…”

    “…CD4(+) T cell–specific IL-4Rα (Lck(cre)IL-4Rα(−/lox)) deficient BALB/c mice were generated and characterized to elucidate the importance of IL-4Rα signaling during cutaneous leishmaniasis in the absence of IL-4–responsive CD4(+) T cells. …”

    “…CONCLUSIONS: There was no correlation between clinical signs and pathological changes and immunological and parasitological findings in the gastrointestinal tract in canine visceral leishmaniasis. However, jejunum showed a lower parasite load with increased frequency and expression of CD11b, TLR9, CD14/CD11b/TLR9 receptors and IL-10 and TNF-α cytokines. …”

    “…BACKGROUND: Phlebotomus papatasi vectors zoonotic cutaneous leishmaniasis. Previous expression of recombinant P. papatasi acetylcholinesterase (PpAChE1) revealed 85% amino acid sequence identity to mosquito AChE and identified synthetic carbamates that effectively inhibited PpAChE1 with improved specificity for arthropod AChEs compared to mammalian AChEs. …”
