Clinical Outcomes of MDS Patients Who Were Allogeneic Hematopoietic Stem Cell Transplant Candidates but Did Not Proceed with Transplantation
In conclusion, using a unique cohort of patients who were referred for a donor search, our study in real-world practice demonstrates that transplant eligible MDS patients (at the time of donor search) who do not undergo alloHCT have worse survival outcomes compared to those undergoing transplantation. A prospective biologic assignment study is currently underway by the BMT CTN (#1102) to more definitively determine the impact and relative benefits of alloHCT in patients (≥50 years old) with Int2/high-risk de novo MDS.DisclosuresKhaled: Alexion: Consultancy, Speakers Bureau; Daiichi: Consultancy; Juno: Other: Travel Fund...

Discovery of novel Flt3 inhibitory chemotypes through extensive ligand-based and new structure-based pharmacophore modelling methods
Publication date: Available online 22 January 2019Source: Journal of Molecular Graphics and ModellingAuthor(s): Reem Fawaz Abutayeh, Mutasem O. TahaAbstractFlt3 is an oncogenic kinase involved in different types of leukemia. It is most prominently associated with acute myeloid leukemia (AML). Flt3-specific inhibitors have shown promising results in interfering with AML prompting us to model this interesting target. We implemented ligand-based, QSAR-guided, pharmacophore exploration combined with novel structure-based computational workflow based on docking-based comparative intermolecular contacts analysis (db-CICA) combin...

Poly-ICLC, a TLR3 Agonist, Induces Transient Innate Immune Responses in Patients With Treated HIV-Infection: A Randomized Double-Blinded Placebo Controlled Trial
Conclusions: These finding suggest that Poly-ICLC could be safely used for inducing transient innate immune responses in treated HIV+ subjects indicating promise as an adjuvant for HIV therapeutic vaccines. Trial Registration: www.ClinicalTrials.gov, identifier: NCT02071095. Introduction Innate immune dysregulation during HIV infection hinders the formation of anti-HIV adaptive immunity (1–6) resulting in rampant viral dissemination and progression to AIDS. Adherence to combination anti-retroviral therapy (cART) regimens controls viremia, restores CD4+T cell counts and reverses immune dysfunction to ...

Brain Citrullination Patterns and T Cell Reactivity of Cerebrospinal Fluid-Derived CD4+ T Cells in Multiple Sclerosis
We report many of them for the first time. For the already described citrullinated proteins MBP, GFAP, and vimentin, we could identify additional citrullinated sites. The number of modified proteins in MS white matter was higher than control tissue. Citrullinated peptides are considered neoepitopes that may trigger autoreactivity. We used newly identified epitopes and previously reported immunodominant myelin peptides in their citrullinated and non-citrullinated form to address the recognition of CSF-infiltrating CD4+ T cells from 22 MS patients by measuring proliferation and IFN-γ secretion. We did not detect ...

The Long Pentraxin PTX3 as a Humoral Innate Immunity Functional Player and Biomarker of Infections and Sepsis
In conclusion, this study confirmed in a large and controlled population that PTX3 levels are highly increased in severe sepsis and even more in septic shock, and that impaired normalization or reduction of PTX3 levels in the first days predicts multiorgan dysfunction and risk of mortality. The latter study, and many others, showed that PTX3 concentration dropped immediately following effective treatment during ICU stay, suggesting that monitoring PTX3 levels could be useful to follow responsiveness to therapy (67, 70–72). While there is a general consensus on the increase of PTX3 plasma levels in septic patients...

A Systematic Review on Predisposition to Lymphoid (B and T cell) Neoplasias in Patients With Primary Immunodeficiencies and Immune Dysregulatory Disorders (Inborn Errors of Immunity)
Conclusions Though this is not a comprehensive summary of malignancies in PIDDs, or even lymphoproliferative disease in this area, this review summarizes the Medline-indexed published reports of B and T lymphomas in patients with PIDDs. This report highlights the diversity of malignant lymphoproliferative disorders in setting of PIDDs, and its associated challenges of diagnosis and treatment. The pathological classification and nomenclature for the lymphoid malignancies with variably reported and postulated underlying mechanisms were inconsistent and inadequate for many of these published reports. A wide range of treatmen...

Auranofin, an Anti-rheumatic Gold Drug, Aggravates the Radiation-Induced Acute Intestinal Injury in Mice
Conclusion In this study, we found that a non-toxic dose of auranofin significantly aggravated the severity of the radiation-induced intestinal injury. This suggests that auranofin treatment can be an independent factor that influences the risk of intestinal complications after pelvic or abdominal radiotherapy. Ethics Statement All the protocols used in this study were approved by the Institutional Animal Care and Use Committee of the Korean Institute of Radiological and Medical Sciences (IACUC permit number: KIRAMS217-0007). Author Contributions H-JL, JS, and Y-BL designed the experiments. EL and JK conducted the exp...

Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

The Role of New Technologies in Myeloproliferative Neoplasms
Conclusions The discovery of JAK2V617F mutation in BCR-ABL1-negative MPNs by four different international cooperative groups in 2005 (2–5) led to significant insights on the pathogenesis of these disorders. In fact, this mutation results in a gain-of-function with activation of cytokine and growth factor receptors, and thus of the downstream JAK-STAT pathway (79, 95–98). The JAK2 point mutation in exon 12, present in a small percentage of patients with PV, is able to induce the MPN phenotype through the same pathogenic mechanism (6, 7). In 2006 the MPLW515L/K was reported in ET and PMF patients (44, 45) a...

Fight Aging! Newsletter, September 9th 2019
We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

Fight Aging! Newsletter, September 5th 2022
Conclusion Coupled with the animal data, and the existing human trial data for safety, the results here suggests that someone should run a formal, controlled trial of flagellin immunization in older people, 65 and over. The goal would be to see whether (a) this sort of outcome holds up in a larger group of people, and (b) there is a meaningful impact on chronic inflammation and other parameters of health that are known to be affected by the aging of the gut microbiome. The most interesting part of the data is perhaps the decline in microbial diversity, when considered against the gains elsewhere. Microbial dive...
