Therefore there is a need to develop effective, safe, and cost affordable antileishmanial drug candidates.

Structural aspects of lesional and non-lesional skin microbiota reveal key community changes in leprosy patients from India.

Although skin is the primary affected organ in Leprosy, the role of the skin microbiome in its pathogenesis is not well understood. Recent reports have shown that skin of leprosy patients (LP) harbours perturbed microbiota which grants inflammation and disease progression. Herein, we present the results of nested Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis (PCR-DGGE) which was initially performed for investigating the diversity of bacterial communities from lesional skin (LS) and non-lesional skin (NLS) sites of LP (n = 11).

Genome-Wide Proteomics and Phosphoproteomics Analysis of Leishmania spp. During Differentiation.

Determining variations in protein abundance and/or posttranslational modification as a function of time or upon induction by a signal in a particular cell type is central to quantitative proteomics. Isobaric labeling methodologies now allow for parallel quantification of proteins at various conditions concurrently or multiplexing in relatively quantitative proteomics workflows. Hence, mapping the protein expression profiles of various developmental stages of Leishmania parasites is possible with high-resolution mass spectrometry.

16S rDNA based skin microbiome data of healthy individuals and leprosy patients from India.

Leprosy is an infectious disease that has predilection in skin and peripheral nerves. Skin has its own microbiome, however it is not extensively studied in Indian leprosy patients. Here, by using next-generation 16S rDNA sequencing, we have attempted to assess the skin associated microbial diversity pertaining to affected and unaffected skin of Indian leprosy patients.

A proteomic map of the unsequenced kala-azar vector Phlebotomus papatasi using cell line.

The debilitating disease kala-azar or visceral leishmaniasis is caused by the kinetoplastid protozoan parasite Leishmania donovani. The parasite is transmitted by the hematophagous sand fly vector of the genus Phlebotomus in the old world and Lutzomyia in the new world. The predominant Phlebotomine species associated with the transmission of kala-azar are Phlebotomus papatasi and Phlebotomus argentipes.

The crux and crust of ebolavirus: Analysis of genome sequences and glycoprotein gene.

The recent 2013-15 epidemic of Ebola virus disease (EVD) has initiated extensive sequencing and analysis of ebolavirus genomes. All ebolavirus genomes available until December 2014 have been collated and analyzed in this study to obtain phylogenetic relationship and uncover the variations amongst them. The terminal 'leader' and 'trailer' nucleotide sequences of the genomes were omitted and analysis of the intermediate region accommodating the sole seven genes (hepta-CDS region) of the virus showed relative stability of the genome, including the ones isolated from the current epidemic.

Rifapentine-proliposomes for inhalation: in vitro and in vivo toxicity.

Background: Oral therapy for pulmonary tuberculosis (TB) treatment suffers from the limitation of hepatic metabolism leading insufficient concentration of antitubercular (anti-TB) drugs in alveolar macrophage which harbors Mycobacterium tuberculosis (MTB). Targeted aerosol delivery of antituberculous drug to lung is efficient for treating local lung TB infection.

Objective: The present study was aimed to evaluate rifapentine (RPT) loaded proliposomal dry powder for inhalation (RLDPI) for anti-TBactivity and cytotoxicity in vitro.

Prevalence and subtype analysis of Blastocystis in healthy Indian individuals.

There is a growing interest in subtype (ST) analysis of the intestinal parasite Blastocystis due to its extensive genetic diversity that might reflect differences in pathogenicity. Although essential for reference, few studies are available on Blastocystis in healthy individuals. Moreover, molecular epidemiology data on Blastocystis in India still remain to emerge.

Cellular interactions and photoprotective effects of idebenone-loaded nanostructured lipid carriers stabilized using PEG-free surfactant.

In past years, nanostructured lipid carriers (NLCs) have emerged as novel topical antioxidant delivery systems because of combined positive features of liposomes and polymeric nanoparticles. Here, we seek to unlock the possibility of idebenone (IDB; an antioxidant)-loaded NLCs (IDB-NLCs) cellular interactions such as, viability and uptake, and its photoprotective effects against Ultraviolet-B (UVB)-mediated oxidative stress in immortal human keratinocyte cell line (HaCaT). The two-step preformulation strategy followed by three-level, three-variable, L9 (3(3)) Taguchi robust orthogonal design employed was important in improving IDB-NLCs key physicochemical aspects such as, entrapment efficiency, drug release (sustained), occlusion, skin deposition and physical stability.

Signaling networks in Leishmania macrophages deciphered through integrated systems biology: a mathematical modeling approach.

Network of signaling proteins and functional interaction between the infected cell and the leishmanial parasite, though are not well understood, may be deciphered computationally by reconstructing the immune signaling network. As we all know signaling pathways are well-known abstractions that explain the mechanisms whereby cells respond to signals, collections of pathways form networks, and interactions between pathways in a network, known as cross-talk, enables further complex signaling behaviours. In silico perturbations can help identify sensitive crosstalk points in the network which can be pharmacologically tested.

Immune signal transduction in leishmaniasis from natural to artificial systems: role of feedback loop insertion.

Background: Modulated immune signal (CD14-TLR and TNF) in leishmaniasis can be linked to EGFR pathway involved in wound healing, through crosstalk points. This signaling network can be further linked to a synthetic gene circuit acting as a positive feedback loop to elicit a synchronized intercellular communication among the immune cells which may contribute to a better understanding of signaling dynamics in leishmaniasis.

Methods: Network reconstruction with positive feedback loop, simulation (ODE 15s solver) and sensitivity analysis of CD14-TLR, TNF and EGFR was done in SimBiology (MATLAB 7.
