Early-life stress (ELS), including chronic deprivation of maternal care, exerts persistent life-long effects on animal physiology and behavior, and is associated with several neurodevelopmental disorders. Long-lasting changes in neuronal plasticity and electrophysiology are documented extensively in the animal models of ELS. However, the role of astroglia in the lasting effects of ELS remains elusive. Astrocytes are intricately involved in the regulation of synaptic physiology and behavior. Moreover, astrocytes play a major role in the innate and adaptive immune responses in the central nervous system (CNS). The role of immune responses and neuroinflammation in the altered brain development and persistent adverse effects of ELS are beginning to be explored. Innate immune response in the CNS is characterized by a phenomenon called astrogliosis, a process in which astrocytes undergo hypertrophy, along with changes in gene expression and function. While the immune activation and neuroinflammatory changes concomitant with ELS, or in juveniles and young adults have been reported, it is unclear whether mice subjected to ELS exhibit astrogliosis-like alterations well into late-adulthood. Here, we subjected mice to maternal separation from postnatal day 2 to day 22 and performed comprehensive morphometric analysis of hippocampal astrocytes during late-adulthood. We found that the astrocytes in the stratum radiatum region of the CA1 hippocampal subfield from maternally separated mice exhibit significant hypertrophy as late as 8 months of age, revealing the crucial changes in astrocytes that manifest long after the cessation of ELS. This study highlights the persistence of neuroinflammatory changes in mice exposed to ELS.

ABSTRACT The immune and nervous systems display considerable overlap in their molecular repertoire. Molecules originally shown to be critical for immune responses also serve neuronal functions that include normal brain development, neuronal differentiation, synaptic plasticity, and behavior. We show here that FcγRIIB, a low-affinity immunoglobulin G Fc receptor, and CD3 are involved in cerebellar functions. Although membranous CD3 and FcγRIIB are crucial regulators on different cells in the immune system, both CD3ε and FcγRIIB are expressed on Purkinje cells in the cerebellum. Both CD3ε-deficient mice and FcγRIIB-deficient mice showed an impaired development of Purkinje neurons. In the adult, rotarod performance of these mutant mice was impaired at high speed. In the two knockout mice, enhanced paired-pulse facilitation of parallel fiber-Purkinje cell synapses was shared. These results indicate that diverse immune molecules play critical roles in the functional establishment in the cerebellum.

Biological control provides a safer alternative to reduce the population of agricultural pest. Mirabilis jalapa is one of biopesticides containing chemical substances that have a feeding deterrent property against Spodoptera litura as folifagus insect pest. This study aimed to analyze the humoral and cellular immunes responses of S. litura after exposure to biopesticide extracted from M. jalapa. The measured indicator immune responses were activity of hemocyte, lectin, phenoloxidase (PO), and phagocytic activity. The results showed that the average total hemocyte was different significantly depending on the treatment. Exposure to 0.1% and 0.2% (w/v) of M. jalapa extract increased the total number of hemocytes as much as 38.08% and 64.15%, respectively. Lectin was quickly formed at 0.1% and 0.2% (w/v) concentrations. The amount of PO enzymes was significantly different at sublethal concentrations compared with control samples (P < 0.05). The highest increase in PO activity occurred at 2 h post-treatment and at M. jalapa extract concentrations of 0.2% (592.33 IU/mg) and 0.1% (521.33 IU/mg), whereas the highest concentration of the extract (0.8% w/v) caused a decrease in lectin and PO activities. In terms of phagocytic activity, the proportion of phagocytosis cells were 47.62% in control group, and decreased significanlty in both concentrations exposure.

Affective disorders (AD) including major depressive disorder (MDD) and bipolar disorder (BD) are common mood disorders associated with increased disability and poor health outcomes. Altered immune responses characterized by increased serum levels of pro-inflammatory cytokines and neuroinflammation are common findings in patients with AD and in corresponding animal models. Dendritic cells (DCs) represent a heterogeneous population of myeloid cells that orchestrate innate and adaptive immune responses and self-tolerance. Upon sensing exogenous and endogenous danger signals, mature DCs secrete proinflammatory factors, acquire migratory and antigen presenting capacities and thus contribute to neuroinflammation in trauma, autoimmunity, and neurodegenerative diseases. However, little is known about the involvement of DCs in the pathogenesis of AD. In this review, we summarize the current knowledge on DCs in peripheral immune responses and neuroinflammation in MDD and BD. In addition, we consider the impact of DCs on neuroinflammation and behavior in animal models of AD. Finally, we will discuss therapeutic perspectives targeting DCs and their effector molecules in mood disorders.

AbstractThe target article by Boyer & Petersen (B&P) contributes a vital message: that people have folk economic theories that shape their thoughts and behavior in the marketplace. This message is all the more important because, in the history of economic thought, Homo economicus was increasingly stripped of mental capacities. Intuitive theories can help restore the mind of Homo economicus.
