Chemokine News and Research

RSS

Chemokines are a family of small cytokines, or proteins secreted by cells. Proteins are classified as chemokines according to shared structural characteristics such as small size (they are all approximately 8-10 kilodaltons in size), and the presence of four cysteine residues in conserved locations that are key to forming their 3-dimensional shape.

New antibody treatment blocks immune response to prevent Alzheimer's damage

There is no treatment available today to stop the death of brain cells in neurodegenerative diseases known as tauopathies, including Alzheimer's disease, in which twisted clumps of a protein called tau accumulate in the brain.

Regular exercisers show distinct metabolic and immune signatures in blood

Researchers compared blood samples from 40 regular exercisers and 46 sedentary adults and found differences in metabolites, blood chemistry, and immune cell gene activity. The patterns suggested greater fatty acid use and altered immune signaling among exercisers, but the study could not establish that exercise caused these differences.

Refined starch activates immune pathways after low-carb weight loss

After substantial weight loss on a very-low-carbohydrate diet, participants who switched to a diet rich in refined starch showed greater activation of circulating immune and metabolic pathways than those who continued the low-carbohydrate diet or consumed a high-carbohydrate diet rich in added sugar. Mouse experiments suggested that activation of the complement immune pathway may help explain the inflammatory response associated with starch intake.

Gut infection leaves long-lasting immune ‘memories’ at the brain’s borders in mice

In mice, intestinal infections reshaped dural CD4+ T-cell populations and seeded the brain’s outer meningeal border with antigen-specific memory cells that persisted for months and mounted rapid recall responses to bloodborne antigens. Oral priming was associated with reduced Salmonella spread to the brain and modest cross-protection in an engineered shared-antigen Candida model, although the researchers could not definitively prove that dural CD4+ T cells alone caused the protection.

Researchers traced lifelong obesity resistance in mice back to an early microbial encounter

Natural wild-derived microbiota protected mice against diet-induced obesity across sexes, genetic backgrounds, and age by increasing energy expenditure and promoting a thermogenic program in brown adipose tissue. The effect depended on the immune system’s initial encounter with the microbiota and required CCR2-associated myeloid activity, revealing a long-lasting microbiota-immune-brown fat pathway.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

Glioma microenvironment emerges as key target for future therapies

The prognosis for glioma patients remains extremely poor despite aggressive multimodal standard therapy: maximal safe resection, radiotherapy, and temozolomide chemotherapy, with median survival rarely exceeding 15 to 18 months.

Study provides new insights into how IL-26 reshapes the tumor immune landscape

While cancer cells acquire malignant traits through epigenetic remodeling, it remains unclear how immune-derived inflammatory factors regulate the epigenetics of colorectal cancer cells.

Long-acting HIV prevention tools could help close the gap before a vaccine arrives

A review of non-vaccine HIV interventions highlights the strong preventive effects of long-acting PrEP, sustained ART, U=U, vertical transmission programs, and voluntary medical male circumcision. Gene editing and multispecific antibodies may expand future options, but safety, cost, access, adherence, and implementation barriers remain.

Too little or too much iodine may push immunity off balance

This narrative review finds that adequate iodine supports thyroid hormone signaling, leukocyte metabolism, antioxidant defenses, and antimicrobial activity in humans and domesticated mammals. Both deficiency and sustained excess may impair immunity or promote thyroid inflammation, but precise immune-specific intake thresholds remain uncertain.

Maternal diet may subtly shape breast milk immune signals

Research indicates that maternal dietary patterns can subtly affect the immune composition of breast milk, with implications for infant immune development.

Reversing macrophage metabolism may improve cancer immunotherapy outcomes

Tumor-associated macrophages (TAMs) are among the most abundant immune cells in the tumor microenvironment.

Melatonin dampens fetal membrane inflammation linked to preterm birth

Melatonin reduced infection-related inflammation in human fetal membranes in an ex vivo model. The study suggests that this effect works partly through melatonin receptors and by suppressing the TLR4/MyD88/NF-κB pathway.

Skin barrier monitoring predicts necrosis after skin flap surgery

Random-pattern skin flaps (RPSFs) receive blood mainly from small subcutaneous vessels rather than a defined axial vessel, leaving them vulnerable to ischemia and hypoxia after surgery.

Prime and pull vaccine approach prevents genital herpes infection

Genital herpes is a lifelong infection. While available treatments can manage symptoms, they cannot cure the infection or prevent transmission.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Hypoxia-gated AAV enables targeted treatment for advanced NSCLC

Adeno‑associated virus (AAV) vectors offer safety and durable expression but lack tumor specificity. This hypothesis proposes an NSCLC‑directed, hypoxia‑responsive AAV platform that integrates MGS4 peptide‑guided capsid targeting with dual hypoxia‑responsive element (HRE)‑gated promoters driving Q‑CXCL9‑Fc (chemokine) and miR‑30‑based shRNA against mesothelin (MSLN).

DNA-guided CRISPR system targets RNA and expands Cas12 beyond gene editing

Researchers developed ΨDNA, a DNA-based CRISPR guide that allows Cas12 enzymes to target RNA with high specificity while retaining compatibility with DNA-editing workflows. The platform detected HCV RNA in clinical samples and enabled programmable RNA knockdown, multiplex targeting, and RNA modification in human cells.
