Vaginal mucositis related to immunotherapy in endometrial cancer.

Gynecol Oncol Rep 2021 May 31;36:100742. Epub 2021 Mar 31.

Rutgers Cancer Institute of New Jersey, United States.

Immunotherapy, specifically immune checkpoint inhibitors (ICPi), has revolutionized our approach to treating all solid tumors, including gynecologic malignancies. Compared to standard chemotherapy, the adverse events associated with immunotherapies, are often mild and localized, although more severe systemic responses can also occur. While dermatitisdermatitis is a most commonly reported side effect of ICPi therapy, cutaneous toxicities have a range of clinical manifestations and can provide a challenge in an otherwise favorable treatment protocol.

A Phase I study of alpelisib in combination with trastuzumab and LJM716 in patients with -mutated HER2-positive metastatic breast cancer.

Clin Cancer Res 2021 May 4. Epub 2021 May 4.

Medicine, Memorial Sloan-Kettering Cancer Center/Weill Cornell Medical College

Purpose: Activating mutations in PIK3CA promote resistance to HER2-targeted therapy in breast cancer, however inhibition of PI3K alone leads to escape via feedback upregulation of HER3. Combined inhibition of HER2, HER3 and PI3K overcomes this mechanism preclinically.

Experimental Design: This phase I study investigated the maximum tolerated dose (MTD) of alpelisib given in combination with trastuzumab and LJM716 (a HER3-targeted antibody) in patients with PIK3CA-mutant HER2-positive metastatic breast cancer (MBC) using the continual reassessment method.

Dorsal striatum and the temporal expectancy of an aversive event in Pavlovian odor fear learning.

Neurobiol Learn Mem 2021 Apr 26:107446. Epub 2021 Apr 26.

Lyon Neuroscience Research Center, INSERM U1028, CNRS UMR 5292, University Lyon 1, Lyon 69366, France.

Interval timing, the ability to encode and retrieve the memory of intervals from seconds to minutes, guides fundamental animal behaviors across the phylogenetic tree. In Pavlovian fear conditioning, an initially neutral stimulus (conditioned stimulus, CS) predicts the arrival of an aversive unconditioned stimulus (US, generally a mild foot-shock) at a fixed time interval. Although some studies showed that temporal relations between CS and US events are learned from the outset of conditioning, the question of the memory of time and its underlying neural network in fear conditioning is still poorly understood.

Diversity of phosphoinositide binding proteins in Entamoeba histolytica.

Parasitol Int 2021 Apr 24;83:102367. Epub 2021 Apr 24.

Department of Biomedical Chemistry, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan. Electronic address:

Phosphatidylinositol phosphates (PIPs, phosphoinositides) are localized to the membranes of all cellular compartments, and play pivotal roles in multiple cellular events. To fulfill their functions, PIPs that are located to specific organelles or membrane domains bind to and recruit various proteins in spatiotemporal specific manner via protein domains that selectively bind to either a single or an array of PIPs. In Entamoeba histolytica, the human intestinal protozoan parasite, PIPs and PIP-binding proteins have been shown to be involved in their virulence-associated mechanisms such as cell motility, vesicular traffic, trogo- and phagocytosis.

Paraneoplastic Neurological Syndromes and Beyond Emerging With the Introduction of Immune Checkpoint Inhibitor Cancer Immunotherapy.

Front Neurol 2021 9;12:642800. Epub 2021 Apr 9.

Departments of Neurology and Laboratory Medicine and Pathology, Mayo Clinic College of Medicine, Rochester, MN, United States.

Paraneoplastic neurological syndromes are more commonly seen with malignancies such as small cell lung cancer, thymoma, gynecological malignancies, and breast cancer as well as seminoma. With the introduction of immune checkpoint inhibitor (ICI) cancer immunotherapy we see an increase of autoimmune neurological complications in patients with malignancies not traditionally associated with paraneoplastic neurological syndromes, such as melanoma and renal cell carcinoma. Immune checkpoint inhibitors enhance antitumor immune responses resulting often in immune-related adverse effects that can affect any organ, including the central and peripheral nervous system, neuromuscular junction and muscle.

Contingency of semantic generalization on episodic specificity varies across development.

Curr Biol 2021 Apr 19. Epub 2021 Apr 19.

Department of Psychology, Temple University, Philadelphia, PA, USA.

Semantic memory-general knowledge of ideas and concepts-includes generalization processes that support inference. Episodic memory, on the other hand, preserves the specificity of individual events by binding together unique combinations of elements from an episode and relies on pattern separation to distinguish similar experiences. These two memory systems play complementary roles, supporting different mnemonic goals, but the nature and extent of their interdependence is unclear. Read More
