Allergen immunotherapy, cancer, and immune disorders
Purpose of review The purpose of this review is to provide an update on the intriguing relationships between allergies, allergen immunotherapy, cancer, and immune disorders. Allergic diseases and cancer are increasing in incidence and prevalence and a potential relationship, or not, between these diseases have been suggested for many years. Recent findings Recent findings suggest that there may be some causative effects between certain types of cancer and allergic diseases, as described in the text. Some types of cancer may be more linked to the presence of an allergic disease, than others. However, epigenetic f...

Eosinophils in the pathogenesis of pancreatic disorders
AbstractEosinophils comprise approximately 1 –4% of total blood leukocytes that reside in the intestine, bone marrow, mammary gland, and adipose tissues to maintain innate immunity in healthy individuals. Eosinophils have four toxic granules known as major basic protein (MBP), eosinophil cationic protein (ECP), eosinophil peroxidase (EPO), a nd eosinophil-derived neurotoxin (EDN), and upon degranulation, these granules promote pathogenesis of inflammatory diseases like allergy, asthma, dermatitis, and gastrointestinal disorders. Additionally, the role of eosinophils is underscored in exocrine disorders including pancreat...

Allergic Contact Dermatitis To Fentanyl TTS With Good Tolerance To Systemic Fentanyl.
CONCLUSION: We present the case of allergic contact dermatitis (ACD) due to hypersensitivity to fentanyl with good tolerance to buprenorphine. Positive PT in this patient suggests a type IV hypersensitivity mechanism. Allergic reactions to opioids are frequently immediate, but delayed reactions could appear, especially when the drug is administered topically. PMID: 31131754 [PubMed - as supplied by publisher]

Innate Lymphoid Cells: Expression of PD-1 and Other Checkpoints in Normal and Pathological Conditions
Conclusions and Future Perspectives It is now evident that NK/ILC family plays a pivotal role in the immune defenses. Recent studies in murine and human settings demonstrated that the expression of several inhibitory checkpoints, that may be detrimental in the tumor context, is not restricted to T lymphocytes, revealing an important, yet poorly appreciated, contribution of their expression on innate immune cells. Thus, in the recent years different immunotherapy approaches, based on the blockade of inhibitory NK cell receptors, have been developed in order to unleash NK cell cytotoxicity. This is particularly important in...

The Potential Role of T Helper Cell 22 and IL-22 in Immunopathogenesis of Multiple Sclerosis
Conclusion Recent evidence shows changes in frequency and function of Th22 and its cytokine IL-22 in patients with MS, which suggests a potential relationship between Th22 cells, IL-22 levels, and the development and disease course of MS and its response to treatment. How Th22 cells and IL-22 levels affect the disease course of MS requires further elucidation. Additional studies on the immunopathogenesis of MS, specifically the roles Th22 cells and IL-22 cytokines may play in disease progression, are warranted and may lead to the development of new therapeutic strategies for treating neuro-inflammatory diseases, such as MS...
