Malignancy in common variable immune deficiency: report of two rare cases of gastrointestinal malignancy and a review of the literature.

In this study we review the occurrence of malignancy in patients with CVID and postulate mechanisms that may be involved indigent to this disease. We will also review the role of replacement immunoglobulin and discuss cancer screening in these high risk individuals. PMID: 22746346 [PubMed - indexed for MEDLINE]

We report 3 deleterious nsSNPs (F78L, Q644R and S646F) in the coding region of JAK1 with predicted structure and function linking to diseases. However, further studies are needed to validate this preliminary observation. PMID: 31831954 [PubMed]

Myeloid-derived suppressor cells (MDSCs), one heterogeneous population of immature myeloid cells, have suppressive function on immune response during tumor, inflammation, infection and autoimmune diseases. The molecular mechanism underlying expansion and function of MDSCs is becoming appreciated to manipulate immune response in the diseases. MicroRNA (miRNAs) as one short noncoding RNAs, are involved in regulating cell proliferation, differentiation and maturation. However, it needs to be further studied how miRNAs mediate the development and function of MDSC in association with cancer and other diseases. In the review, we...

Autoimmune hypothalamic-pituitary-adrenal axis (HPA) diseases induced by checkpoint inhibitors are being increasingly recognized. We aimed to characterize the spectrum of checkpoi...

Monocyte chemoattractant protein-1 (MCP-1/CCL2) is renowned for its ability to drive the chemotaxis of myeloid and lymphoid cells. It orchestrates the migration of these cell types both during physiological immune defense and in pathological circumstances, such as autoimmune diseases including rheumatoid arthritis and multiple sclerosis, inflammatory diseases including atherosclerosis, as well as infectious diseases, obesity, diabetes, and various types of cancer. However, new data suggest that the scope of CCL2's functions may extend beyond its original characterization as a chemoattractant. Emerging evidence shows that i...

Publication date: Available online 10 December 2019Source: Trends in Pharmacological SciencesAuthor(s): Yang Liu, Pan ZhengA major paradigm in cancer immunotherapy is the use of checkpoint inhibitors to break regulatory mechanisms that usually guard the host against autoimmune diseases. CTLA-4-targeting immunotherapy was the first example that helped establish this paradigm. However, the clinically tested anti-CTLA-4 antibodies exhibit suboptimal efficacy but high toxicity. Recent studies have demonstrated that immunotherapy-related adverse events (irAE) and the cancer immunotherapeutic effect (CITE) represent distinct and...

Conclusions: Survey participants demonstrated a wide variety of responses indicating their understanding of vitamin D testing and supplementation. Although providers estimate a high deficiency rate, many do not routinely check vitamin D. When they do check, there is no standard indication for testing or supplementation and many believe this to be the role of the pediatrician or endocrinologist. More studies are needed to provide a standardized protocol for vitamin D testing and supplementation in the pediatric orthopaedic literature. Clinical Relevance: POSNA survey.

(Yale University) In the last decade, scientists discovered that blocking a key regulator of the immune system helped unleash the body's natural defenses against several forms of cancer, opening up a new era of cancer immunotherapy. Now Yale scientists have essentially flipped this script and found that when impaired a molecularly similar regulator can cause the damaging immune system attacks on skin and organs that are the hallmark of the autoimmune disease lupus.

Publication date: Available online 9 December 2019Source: Journal of Theoretical BiologyAuthor(s): Luis F. Ponce, Karina García-Martínez, Kalet LeónAbstractIL-1 system is involved in the induction and maintenance of chronic inflammation associated with several autoimmune diseases and cancer, mainly due to its capacity to promote the secretion of inflammatory mediators. For this reason, several intracellular and extracellular mechanisms for this system have been fixed during the evolution. In spite of the large description of molecular interactions between IL-1 ligands and receptors, little is known abo...

CONCLUSION: The most potent flavonoids in inflammation that modify immune responses are apigenin, quercetin and Epigallocatechin-3-Gallate (EGCG) although, other compounds are still under study and cannot be excluded. The most relevant patents concerning the use of flavones and other polyphenols were revised. A promising future of these compounds in different therapies is discussed.
