Abstract

Anti-social behaviors and social deficits induced mental disorders are critical problems in our society today. Social behaviors and interactions are shaped by experience, hereditary components (genes, hormones and neuropeptides) and environmental factors (photoperiods and metabolic signals). In addition to the classical gonadotropin-releasing hormone, RFamide peptides, kisspeptin and gonadotropin-inhibiting hormone are emerging as important regulators of the reproductive axis. These neuropeptides are evolutionarily conserved and are regulated by environmental factors. In this Research Topic, we advocate more recent advances in reproductive neuropeptides and sex steroids in the domains of social behavior including sexual and parental behavior, aggression, stress and anxiety. Using multiple species model, we also review how genes and the neuroendocrine system interact at the cell and organismic levels to contribute to social behavior in particular the epigenetic genomic changes caused by early life environment. We provide comprehensive insights of distinct neural networks and how cellular and molecular events in the brain regulate social behavior from a comparative perspective.

Abstract

The phenotype of a plant in response to a stress condition is the reflection of the molecular responses in different cell-types composing the plant. The multicellular complexity represents a challenge when accessing specific responses of each cell or cell type composing the plant. To overcome this difficulty and allow the clear characterization of the plant cell molecular mechanisms, the research community is now focusing on studying a single cell and single cell-types. The isolation of plant single cells is limited by the cell wall that confers the rigidity of the plant and its overall structure. Various methods have been developed for isolating plant cells (e.g. laser capture microdissection; cell sorting of Green Fluorescent Protein (GFP)-tagged protoplasts, differential protoplastization of cells such as guard cells, isolation of easily accessible cell types such as cotton fiber, pollen cells, trichomes and root hair cells). The development of these innovative approaches to isolate single plant cells or cell-types combined with the application of sensitive and high-throughput technologies allows a better analysis of the developmental processes and response to environmental stresses. Ultimately, single plant cell and cell-type biology will lead to establishment of more reliable and accurate -molecular regulatory networks at the resolution of basic life unit. The goal of this Research Topic is to cover new technological and biological advances in the study of plant single cell, cell-type and systems biology.

Abstract

Understanding the factors that create and maintain social inequalities is a core question in social psychology. Research has so far mainly focused on the role of individual stereotyping, prejudice and discrimination. However, there is growing evidence that, beyond the “biased” acts of prejudiced individuals, structural factors related to the very functioning of institutions and organizations can play a role in the reproduction of social inequalities. Indeed, in industrialized countries, society is structured in a way that reflects the perspective of, is organized by, and benefits the dominant groups. In this Research Topic, we propose to bring together researchers who study how institutional ideologies and practices promote norms, rules and opportunities that favor dominant groups and disadvantage dominated groups. This question can be tackled by work investigating how institutional practices (e.g., grading, tracking, recruitment, …) and ideologies (e.g., meritocracy, individualism, protestant work ethic, …) shape the psychological experience of (dis)advantaged people. Moreover, another interesting venue is represented by work investigating how the institutional practices and ideologies are enacted by the agents (e.g., teachers, recruiters, leaders, …). Taking the perspective of agents allows to investigate how institutional functioning constrains the actual opportunities they provide to (dis)advantaged individuals. This could also highlight how institutional ideologies and practices are incorporated by agents, thus revealing mechanisms of change vs. perpetuation of the institutional functioning.

Abstract

Neuroendocrinology is the discipline that investigates the interplay between the nervous and endocrine systems i.e. the control of endocrine glands by the central and peripheral nervous systems, the action of hormones on nerve cells and the production of hormones by the nervous system. The present Research Topic is a compilation of contributions stemming from the 8th International Congress of Neuroendocrinology (ICN2014) held in Sydney, Australia, that illustrates various facets of current neuroendocrine research.
