Transcriptional landscape of mouse-aged ovaries reveals a unique set of non-coding RNAs associated with physiological and environmental ovarian dysfunctions.

Cell Death Discov 2018 5;4:112. Epub 2018 Dec 5.

1Department of Science and Technology, University of Sannio, Via Port'Arsa 11, 82100 Benevento, Italy.

The progressive and physiological decline in ovarian function depends on the rate of follicular loss by atresia, contributing to the reduction in ovarian reserve. Genetics and environmental factors play important roles in ovarian senescence and in the onset of ovarian dysfunctions such as diminished ovarian reserve. A better understanding of the mechanisms underlying ovarian aging and their regulation by genetic and environmental factors is needed to evaluate ovarian reserve and to predict fertility potential by identification of more accurate and less invasive markers.

Robust adaptive immune response against infection marked by low parasitemia in a murine model of sickle cell disease.

Blood Adv 2018 Dec;2(23):3462-3478

Laboratory of Complement Biology and.

The intraerythrocytic parasite is the number 1 cause of transfusion-transmitted infection and can induce serious, often life-threatening complications in immunocompromised individuals including transfusion-dependent patients with sickle cell disease (SCD). Despite the existence of strong long-lasting immunological protection against a second infection in mouse models, little is known about the cell types or the kinetics of protective adaptive immunity mounted following infection, especially in infection-prone SCD that are thought to have an impaired immune system. Here, we show, using a mouse infection model, that infected wild-type (WT) mice mount a very strong adaptive immune response, characterized by (1) coordinated induction of a robust germinal center (GC) reaction; (2) development of follicular helper T (T) cells that comprise ∼30% of splenic CD4 T cells at peak expansion by 10 days postinfection; and (3) high levels of effector T-cell cytokines, including interleukin 21 and interferon γ, with an increase in the secretion of antigen (Ag)-specific antibodies (Abs).

Department of Laboratory Medicine and Pathology, Center for Transfusion Medicine and Cellular Therapies, Emory University School of Medicine, Atlanta, GA, United States.

Red blood cell (RBC) alloimmunization represents a significant immunological challenge for some patients. While a variety of immune constituents likely contribute to the initiation and orchestration of alloantibodies to RBC antigens, identification of key immune factors that initiate alloantibody formation may aid in the development of a therapeutic modality to minimize or prevent this process. To define the immune factors that may be important in driving alloimmunization to an RBC antigen, we determined the specific immune compartment and distinct cells that may initially engage transfused RBCs and facilitate subsequent alloimmunization.

The aim of the current study was to assess the changes in hemostatic variables in women with vWD during two phases of the menstrual cycle (follicular and luteal) and to compare it with healthy controls.

Novel immunotherapy approaches to follicular lymphoma.

Hematology Am Soc Hematol Educ Program 2018 Nov;2018(1):194-199

Department of Lymphoma/Myeloma, The University of Texas MD Anderson Cancer Center, Houston, TX.

Follicular lymphoma (FL) remains a lymphoma subtype that is remarkably sensitive to immunotherapy-based treatment strategies. Anti-CD20 antibody therapy administered as a single agent and in combination as a first-line treatment and at relapse continues to be the most broadly used therapy for this disease. Autologous and allogeneic stem cell transplantation provide meaningful durable remissions for patients with FL. Read More

Sequencing of therapies in relapsed follicular lymphoma.

Hematology Am Soc Hematol Educ Program 2018 Nov;2018(1):189-193

Division of Hematology and Medical Oncology, Meyer Cancer Center, Weill Cornell Medicine and NewYork-Presbyterian Hospital, New York, NY.

Follicular lymphoma (FL) is an incurable but treatable disease with vast treatment options. Despite the abundance of efficacious treatment modalities, there is no universally agreed upon standard approach to treatment, particularly in the relapsed/refractory setting. There is an increasing need for more robust and clinically available tools to risk-stratify patients and identify those likely to experience early relapse, which is currently recognized as the unmet need in FL.

Where to start? Upfront therapy for follicular lymphoma in 2018.

Hematology Am Soc Hematol Educ Program 2018 Nov;2018(1):185-188

Department of Hematology and Oncology, Winship Cancer Institute, Emory University, Atlanta, GA.

The initial approach to the management of follicular lymphoma (FL) is challenging for patients and physicians. Most FL patients present with minimal symptoms; given the lack of a survival benefit to early treatment in this population, a period of observation without therapy is often appropriate. Once there is disease progression beyond low-tumor-burden criteria or symptoms prompting intervention, patients may be considered for an array of potential treatment options. Read More

Intrinsic properties of human germinal center B cells set antigen affinity thresholds.

Sci Immunol 2018 Nov;3(29)

Laboratory of Immunogenetics, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Rockville, MD 20852, USA.

Protective antibody responses to vaccination or infection depend on affinity maturation, a process by which high-affinity germinal center (GC) B cells are selected on the basis of their ability to bind, gather, and present antigen to T follicular helper (T) cells. Here, we show that human GC B cells have intrinsically higher-affinity thresholds for both B cell antigen receptor (BCR) signaling and antigen gathering as compared with naïve B cells and that these functions are mediated by distinct cellular structures and pathways that ultimately lead to antigen affinity- and T cell-dependent differentiation to plasma cells. GC B cells bound antigen through highly dynamic, actin- and ezrin-rich pod-like structures that concentrated BCRs. Read More

Follicular fluid humanin concentration is related to ovarian reserve markers and clinical pregnancy after IVF-ICSI: a pilot study.

Reprod Biomed Online 2018 Nov 23. Epub 2018 Nov 23.

Family Planning Research Institute, Tongji Medical College, Huazhong University of Science and Technology, No.13 Hang Kong Road, Wuhan Hubei 430030, China; Reproductive Medicine Center, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China.

Research Question: Is humanin present in the human ovary and follicular fluid? What relationship exists between humanin concentration in the follicular fluid and ovarian reserve and clinical outcomes after IVF and intracytoplasmic sperm injection (ICSI)?

Design: Follicular fluid samples were collected from 179 patients undergoing their first IVF or ICSI cycle during oocyte retrieval. Ovarian tissues were collected from two patients undergoing surgery for ovarian cysts. Ovarian humanin localization was analysed using immunofluorescence staining. Read More

Subcapsular Sinus Macrophages: The Seat of Innate and Adaptive Memory in Murine Lymph Nodes.

Trends Immunol 2018 Nov 27. Epub 2018 Nov 27.

Immunology Division, Garvan Institute of Medical Research, Sydney, Australia; St Vincent's Clinical School, Faculty of Medicine, University of New South Wales, Sydney, Australia. Electronic address:

Subcapsular sinus (SCS) macrophages are strategically positioned at the lymph-tissue interface in the lymph node to trap and present antigen to B cells. Recent murine data has shown that SCS macrophages also prevent the systemic spread of lymph-borne pathogens and are capable of activating a diverse range of innate effector and adaptive memory cells, including follicular memory T cells and memory B cells (B), that are either pre-positioned or rapidly recruited to the subcapsular niche following infection and inflammation. Furthermore, B are rapidly reactivated to differentiate into plasma cells in subcapsular proliferative foci (SPF). Read More
