Phage to ESKAPE: Personalizing Therapy for MDR Infections-A Comprehensive Clinical Review

The proliferation of multidrug-resistant (MDR) ESKAPE pathogens—Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.—constitutes a critical global health crisis, rendering conventional antibiotics increasingly ineffective. This comprehensive review evaluates the re-emerging potential of bacteriophage therapy as a personalized treatment for infections caused by these organisms. Phages, being viruses that spec...

Therapeutic properties of mesenchymal stromal/stem cells: The need of cell priming for cell-free therapies in regenerative medicine

Mesenchymal stromal/stem cells (MSCs) are multipotent adult stem cells that support homeostasis during tissue regeneration. In the last decade, cell therapies based on the use of MSCs have emerged as a promising strategy in the field of regenerative medicine. Although these cells possess robust therapeutic properties that can be applied in the treatment of different diseases, variables in preclinical and clinical trials lead to inconsistent outcomes. MSC therapeutic effects result from the se...

NF-κB localization in multiple myeloma plasma cells and mesenchymal cells

Several reports demonstrated that the activation of Nuclear Factor-kappa B NF-κB is essential for the pathogenesis of multiple myeloma (MM). We analyzed the nuclear localization of NF-κB in MM-cells derived from 60 different patients with MM at presentation and in relapse, as well as in three myeloma cell lines. Nuclear localization (the active form) of NF-κB was detected in only one MM-sample from a refractory patient and in two samples from relapsed patients, while all the other samples, in...

Resistance of papillary thyroid cancer stem cells to chemotherapy

Thyroid carcinoma is the most common endocrine neoplasm, with the highest mortality rate of all the endocrine cancers. Among the endocrine malignancies, ~80% are papillary thyroid carcinomas (PTCs). In the initiation and progression of this tumor, genetic alterations in the mitogen-associated protein kinase pathway, including RAS point mutations, RET/PTC oncogene rearrangements and BRAF point mutations, play an important role, particularly in deciding targeted therapy. In the present study, a...

Interleukin 10 increases CCR5 expression and HIV infection in human monocytes

The immunosuppressive and antiinflammatory cytokine interleukin (IL) 10 selectively upregulates the expression of the CC chemokine receptors CCR5, 2, and 1 in human monocytes by prolonging their mRNA half-life. IL-10-stimulated monocytes display an increased number of cell surface receptors for, and better chemotactic responsiveness to, relevant agonists than do control cells. In addition, IL-10-stimulated monocytes are more efficiently infected by HIV BaL. This effect was associated to the e...
