Adrenomedullin (AM) and proadrenomedullin N-terminal 20 peptide (PAMP) are small peptides derived from a common precursor, pre-proadrenomedullin. Although AM and PAMP share hypotensive effects in the cardiovascular system, the peptides also exert diverse and distinct effects on endocrine physiology, innate immunity, cytoskeletal biology and receptor signaling pathways. Tremendous knowledge has been gleaned from the study of several genetic animal models of AM deletion or overexpression, some of which also simultaneously delete the coding region for PAMP peptide.

Pomacea canaliculata is a freshwater snail with interesting biological features that include invasiveness, human parasite hosting and adult regeneration. Its immune system may represent the target for strategies aimed at controlling the spread of the snail population and its hosting of the human parasite Angiostrongylus cantonensis. Moreover, immune functions likely have a role in the snail's ability to wound heal and regenerate. Read More

Intracellular NLR (nucleotide-binding leucine-rich repeat)-type immune receptors are a fundamental aspect of plant immune systems. As infection occurs at foci, activation of immune responses is typically non-uniform and non-synchronized, hampering the systematic dissection of their cellular effects and determining their phasing. We investigated the Potato NLR Rx1 using the CESSNA (Controlled Expression of effectors for Synchronized and Systemic NLR Activation) platform. Read More

Tilorone hydrochloride, a low-molecular-weight synthetic compound, induces interferon production and has been reported to have both antiviral and antitumor activities. Here, we have demonstrated the ability of tilorone to activate NK cells and specific subpopulations of cytotoxic CD4+ and CD8+ T lymphocytes that recognize immune-evasive tumor cells and kill them via the FasL-Fas interaction. We have also performed a comparative analysis of characteristics between lymphocytes activated in the fraction of human peripheral blood mononuclear cells (PBMCs) upon treatment with different stimulants of the immune response: tilorone, innate immunity protein Tag7, and cytokine IL-2, a regulator of adaptive immunity.

Under homeostatic conditions, dendritic cells (DCs) continuously patrol the intestinal lamina propria. Upon antigen encounter, DCs initiate C-C motif chemokine receptor 7 (CCR7) expression and migrate into lymph nodes to direct T cell activation and differentiation. The mechanistic underpinnings of DC migration from the tissues to lymph nodes have been largely elucidated, contributing greatly to our understanding of DC functionality and intestinal immunity.

Toll-like receptors (TLRs) play critical roles in host defence following recognition of conserved microbial- and host-derived components, and their dysregulation is a common feature of various inflammation-associated cancers, including gastric cancer (GC). Despite the recent recognition that metabolic reprogramming is a hallmark of cancer, the molecular effectors of altered metabolism during tumorigenesis remain unclear. Here, using bioenergetics function assays on human GC cells, we reveal that ligand-induced activation of TLR2, predominantly through TLR1/2 heterodimer, augments both oxidative phosphorylation (OXPHOS) and glycolysis, with a bias towards glycolytic activity.

Immune-deficient patients depend on the antibodies in pooled human immunoglobulin G (IgG) preparations to remain free from serious infections. The potency of IgG preparations is therefore an ongoing concern.

Primary immunodeficiency (PID) diseases result from genetic defects of the immune system that increase a patient's susceptibility to infections. The types of infections that occur in patients with PID diseases are dictated largely by the nature of the immunodeficiency, which can be defined by dysfunction of cellular or humoral defenses. An increasing number of PID diseases, including those with both cellular and humoral defects, have antibody deficiency as a major feature, and as a result can benefit from immunoglobulin replacement therapy.

We analyze the interactions between division, mutation and selection in a simplified evolutionary model, assuming that the population observed can be classified into fitness levels. The construction of our mathematical framework is motivated by the modeling of antibody affinity maturation of B-cells in germinal centers during an immune response. This is a key process in adaptive immunity leading to the production of high-affinity antibodies against a presented antigen. Read More

In recent years, the renewed interest in immune cell metabolism has driven the emergence of a research field aimed at studying the role of metabolic processes during innate and adaptive immune responses. Although the specific requirements of myeloid cells after the canonical lipopolysaccharide/TLR4 stimulation have been extensively addressed, recent evidence suggests that this model may not represent a universally accurate metabolic blueprint. Instead, different microbial stimuli, pathogens, or tissue microenvironments trigger specific and complex metabolic rewiring of myeloid cells. Read More

The interaction between intracellular bacterial pathogens with the host immune response can result in multiple outcomes that range from asymptomatic clearance to the establishment of infection. At its core, these interactions result in multiple metabolic adaptations of both the pathogen and its host cell. There is growing evidence that the host metabolic response plays a key role in the development of immune responses against the invading pathogen. Read More

The development of a universal influenza vaccine that can provide a robust and long-lasting protection against a broader range of influenza virus strains is a global public health priority. One approach to improve vaccine efficacy is to use an adjuvant to boost immune responses to the target antigens; nevertheless, the role of adjuvants in the context of influenza vaccines is not fully understood. We have previously developed the K3-schizophyllan (SPG) adjuvant, which is composed of nanoparticulated oligodeoxynucleotides K3, a TLR9 agonist, with SPG, a non-agonistic β-glucan ligand of Dectin-1.

We have previously reported that exercise-related secretion of IL-6 by peripheral blood mononuclear cells is proportionate to body weight, suggesting that IL-6 is gravisensitive and that suboptimal production of this key cytokine may contribute to homeostatic dysregulations that occur during spaceflight. This review details what is known about the role of this key cytokine in innate and adaptive immunity, hematopoiesis, and in bone, muscle and metabolic homeostasis on Earth and in the microgravity of space and suggests an experimental approach to confirm or disavow the role of IL-6 in space-related dysregulations.

Coccidiosis in poultry, caused by protozoan parasites of the genus , is an intestinal disease with substantial economic impact. With the use of anticoccidial drugs under public and political pressure, and the comparatively higher cost of live-attenuated vaccines, an attractive complementary strategy for control is to breed chickens with increased resistance to parasitism.

Disease progression among HIV-1-infected individuals varies widely, but the mechanisms underlying this variability remains unknown. Distinct disease outcomes are the consequences of many factors working in concert, including innate and adaptive immune responses, cell-mediated and humoral immunity, and both genetic and phenotypic factors. Current data suggest that these multifaceted aspects in infected individuals should be considered as a whole, rather than as separate unique elements, and that analyses must be performed in greater detail in order to meet the requirements of personalized medicine and guide optimal vaccine design.
