Myeloid-Derived Suppressor Cells: Ductile Targets in Disease
Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

Expanding Research Capacity in Sub-Saharan Africa Through Informatics, Bioinformatics, and Data Science Training Programs in Mali
Conclusion Bioinformatics and data science training programs in developing countries necessitate incremental and collaborative strategies for their feasible and sustainable development. The progress described here covered decades of collaborative efforts centered on training and research on computationally intensive topics. These efforts laid the groundwork and platforms conducive for hosting a bioinformatics and data science training program in Mali. Training programs are perhaps best facilitated through Africa’s university systems as they are perhaps best positioned to maintain core resources during lapses in sho...

Significance of coexistent granulomatous inflammation and lung cancer
Conclusions Incidental detection of granulomatous inflammation in patients undergoing lung resection for cancer, even in a TB-endemic country, may not require any intervention. Such findings may be due to either mycobacterial infection in the past or ‘sarcoid reaction’ to cancer. Although all patients should have their resected specimen sent for acid-fast bacilli culture and followed up until the culture results are reported, the initiation of the management of such patients as per existing lung cancer management guidelines does not affect their outcome adversely.

Inhibition of Host Heme Oxygenase-1 as an Adjunctive Treatment to Improve the Outcome of Conventional Antibiotic Chemotherapy of Mycobacterium tuberculosis (Mtb) Infection
This invention describes the adjunctive use of heme oxygenase-1 (HO-1) inhibitors to improve the outcome of conventional antibiotic treatment for tuberculosis. The existent standard of care requires prolonged administration of drug. Due to the long duration of treatment, methods that can more rapidly control tuberculosis in patients are clearly needed.NIAID researchers have discovered that inhibition of host HO-1 reducesMycobacterium tuberculosis (Mtb) growth in vivo and, more importantly, when used as an adjunct to conventional chemotherapy, results in a marked improvement in pulmonary bacterial control. In particular, it...

Rifamycin induced leukocytoclastic vasculitis. A rare side-effect of anti-tuberculous chemotherapy
We describe a case of leucocytoclastic vasculitis (LCV) caused by rifamycins.A 53 year old female presented with cough, night sweats and upper lobe nodules. Bronchial-alveolar lavage confirmed fully sensitive mycobacterium tuberculosis (TB).She commenced treatment with rifampicin, isoniazid, ethambutol and pyrizinazmide. At 4 weeks she developed an extensive purpuric rash, malaise and joint aches. There was no evidence of other infections or connective tissue disorders on extensive screening. Her inflammatory markers were elevated. A punch biopsy of her shin demonstrated leukocytoclastic vasculitis of the superficial dermi...

Formulation of Nanoparicles Against TB - A Review.
Authors: Kataria M, Sethi M, Kaur J, Punia S, Kumar K Abstract Tuberculosis is a major public health concern. The present article reviews the current updates on the usage of nanoparticles against tuberculosis and recent patents that could develop into novel therapeutics available to the clinical armamentarium for the TB management. The drug delivery systems involving nanoparticles are suitable against chronic diseases such as tuberculosis. Polymers in many forms like liposomes, dendrimers, Nanoemulsions can be used as synthetic and natural carriers for first line and second line drugs employed for chemotherapy. Not...
