CD123
The interleukin-3 receptor alpha chain (IL-3R), more commonly referred to as CD123, is widely overexpressed in various hematological malignancies, including acute myeloid leukemia (AML), B-cell acute lymphoblastic leukemia, hairy cell leukemia, Hodgkin lymphoma and particularly, blastic plasmacytoid dendritic neoplasm (BPDCN). Importantly, CD123 is expressed at both the level of leukemic stem cells (LSCs) and more differentiated leukemic blasts, which makes CD123 an attractive therapeutic target. Various agents have been developed as drugs able to target CD123 on malignant leukemic cells and on the normal counterpart. Tagraxofusp (SL401, Stemline Therapeutics), a recombinant protein composed of a truncated diphtheria toxin payload fused to IL-3, was approved for use in patients with BPDCN in December of 2018 and showed some clinical activity in AML. Different monoclonal antibodies directed against CD123 are under evaluation as antileukemic drugs, showing promising results either for the treatment of AML minimal residual disease or of relapsing/refractory AML or BPDCN.

Chronic Kidney Disease in the Aging Population
The process of aging population will inevitably increase age-related comorbidities including chronic kidney disease (CKD). In light of this demographic transition, the lack of an age-adjusted CKD classification may enormously increase the number of new diagnoses of CKD in old subjects with an indolent decline in kidney function.

MT1-MMP in Cancer Progression
For over 20 years, membrane type 1 matrix metalloproteinase (MT1-MMP) has been recognized as a key component in cancer progression. Initially, the primary roles assigned to MT1-MMP were the activation of proMMP-2 and degradation of fibrillar collagen. Proteomics has revealed a great array of MT1-MMP substrates, and MT1-MMP selective inhibitors have allowed for a more complete mapping of MT1-MMP biological functions. MT1-MMP has extensive sheddase activities, is both a positive and negative regulator of angiogenesis, can act intracellularly and as a transcription factor, and modulates immune responses. We presently examine the multi-faceted role of MT1-MMP in cancer, with a consideration of how the diversity of MT1-MMP behaviors impacts the application of MT1-MMP inhibitors.

Antioxidant Nutraceuticals against Neurodegenerative Disease
This entry discusses on selected nutraceuticals and their plausible antioxidant effects on Alzheimer and Parkinson disease. Nutraceuticals such as resveratrol, curcumin and vitamin E alleviate oxidative stress by scavenging free radicals, metal chelators, and enhance antioxidant enzymes. Additionally they regulate intracellular signaling such as inflammatory, survival and apoptotic pathways.

Oral Lesions Associated with COVID-19
Some oral lesions have been described in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The possibility has been raised that the buccal lesions observed in patients with the coronavirus disease 2019 (COVID-19) are due to this virus and the patient’s systemic condition. The oral cavity is an accessible and privileged environment for the interaction of SARS-CoV-2 with the mucosal immune system and target cells.

Microbiota in Neurodegenerative Disease
Hundreds of billions of commensal microorganisms live in and on human bodies, most of which colonize the gut shortly after birth and stay there for the rest of human lives. In animal models, bidirectional communications between the central nervous system and gut microbiota (Gut–Brain Axis) have been extensively studied, and it is clear that changes in microbiota composition play a vital role in the pathogenesis of various neurodevelopmental and neurodegenerative disorders, such as Autism Spectrum Disorder, Alzheimer’s disease (AD), Parkinson’s disease (PD), Multiple Sclerosis, Amyotrophic Lateral Sclerosis, anxiety, stress, and so on.

Punicalagin in Cancer Prevention
Punicalagin, present in pomegranate, myrobalan, yellow wood, tropical almond, and pink rock-rose, belongs to ellagitannins - a subgroup of hydrolyzable tannins. In vitro studies, based on cell line experiments, have demonstrated punicalagin anti-cancer actions on human cervical, ovarian, breast, lung, thyroid, colorectal, central nervous system, bone, as well as other cancer types. Punicalagin seems to work through a redirection of signal-transduction pathways from survival and proliferation into cell-cycle arrest, apoptosis, senescence or autophagy (thus compromising neoplastic progression). However, since it readily undergoes hydrolysis releasing e.g. ellagic acid, these might be its products which are responsible for the observed effects. Moreover, when practical application of punicalagin in chemoprevention is addressed, its biotransformation in the human organism should be considered (including both host and microbiome enzymatic impact). Therefore, however promising punicalagin antineoplastic properties seem to be, in vivo-based research should be conducted before translating the results obtained from in vitro studies into practice.

Human Skin Microbiome
The skin is the common coat of the body and is the largest organ of the human organism. Its role is to provide an optimal environment for deeper tissues, by separating them from the external environment, and at the same time ensuring contact with it by exchanging substances and receiving stimuli.

TNF-α Inhibitors and Vaccinations
This entry is a up-to-dated review of the current indications for vaccination in patients on anti-TNF-a therapy. Live attenuated vaccines are always contraindicated, while inactivated vaccines can be safely administered.

Peripheral Nerve Stimulation for Headaches Treatment
Headaches are one of the most common medical complaints worldwide, and treatment is often made difficult because of misclassification. Peripheral nerve stimulation has emerged as a novel treatment for the treatment of intractable headaches in recent years. While high-quality evidence does exist regarding its use, efficacy is generally limited to specific nerves and headache types. While much research remains to bring this technology to the mainstream, clinicians are increasingly able to provide safe yet efficacious pain control.
