|title=Assessment of neuroinflammation in the aging hippocampus using large-molecule microdialysis: Sex differences and role of purinergic receptors.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/33166661
|abstract=Aging is associated with an enhanced neuroinflammatory response to acute immune challenge, often termed "inflammaging." However, there are conflicting reports about whether baseline levels of inflammatory markers are elevated under ambient conditions in the aging brain, or whether such changes are observed predominantly in response to acute challenge. The present studies utilized two distinct approaches to assess inflammatory markers in young and aging Fischer 344 rats. Experiment 1 examined total tissue content of inflammatory markers from hippocampus of adult (3 month), middle-aged (12 month), and aging (18 month) male Fischer (F) 344 rats using multiplex analysis (23-plex). Though trends emerged for several cytokines, no significant differences in basal tissue content were observed across the 3 ages examined. Experiment 2 measured extracellular concentrations of inflammatory factors in the hippocampus from adult (3 month) and aging (18 month) males and females using large-molecule in vivo microdialysis. Although few significant aging-related changes were observed, robust sex differences were observed in extracellular concentrations of [[CCL3]], [[[[CCL2]]0]], and IL-1α. Experiment 2 also evaluated the involvement of the P2X7 purinergic receptor in neuroinflammation using reverse dialysis of the selective agonist BzATP. BzATP produced an increase in IL-1α and IL-1β release and rapidly suppressed the release of [[CXCL1]], [[CCL2]], [[CCL3]], [[[[CCL2]]0]], and IL-6. Other noteworthy sex by aging trends were observed in [[CCL3]], IL-1β, and IL-6. Together, these findings provide important new insight into late-aging and sex differences in neuroinflammation, and their regulation by the P2X7 receptor.

|title=Microglial translational profiling reveals a convergent [[APOE]] pathway from aging, amyloid, and tau.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/30082275
|abstract=Alzheimer's disease (AD) is an age-associated neurodegenerative disease characterized by amyloidosis, tauopathy, and activation of microglia, the brain resident innate immune cells. We show that a RiboTag translational profiling approach can bypass biases due to cellular enrichment/cell sorting. Using this approach in models of amyloidosis, tauopathy, and aging, we revealed a common set of alterations and identified a central [[APOE]]-driven network that converged on [[CCL3]] and [[CCL4]] across all conditions. Notably, aged females demonstrated a significant exacerbation of many of these shared transcripts in this [[APOE]] network, revealing a potential mechanism for increased AD susceptibility in females. This study has broad implications for microglial transcriptomic approaches and provides new insights into microglial pathways associated with different pathological aspects of aging and AD.

|title=Time-Dependent Changes in Local and Serum Levels of Inflammatory Cytokines as Markers for Incised Wound Aging of Skeletal Muscles.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/29760352
|abstract=Wound age estimation is an important research field in forensic pathology. The expression levels of cytokines in the incised skeletal muscle were analyzed using a mouse model to explore the applicability for wound aging. A 5-mm long incisional wound was made at the biceps femoris muscle, and the muscle and serum were sampled at 6, 12, 24 and 48 hours after injury. Using a multiplex bead-based immunoassay, we measured the tissue levels of nine cytokines (IL-1β, IL-6, IL-7, [[CCL2]], [[CCL3]], [[CCL4]], [[CXCL1]], [[CXCL2]], and [[CXCL1]]0), which are all involved in the pathways of inflammatory response and tissue injury. Immunoassay of post-injury muscle samples revealed significant increases in the levels of six cytokines, except for [[CCL3]], [[CCL4]] and IL-7, at 6 hours after injury. The elevated tissue levels of these six cytokines were maintained during 48 hours after injury, although the levels of IL-6 and [[CXCL1]] were significantly decreased at 12 hours. In case of [[CCL3]], its tissue levels were increased only at 12 hours. By contrast, [[CCL4]] and IL-7 levels were increased only at 48 hours. Moreover, serum levels of most cytokines, except for [[CXCL1]], remained unchanged during 24 hours after injury, followed by significant increases at 48 hours. Serum [[CXCL1]] levels were increased at 6 hours and then decreased to the basal levels. Thus, the significant increase in the muscle levels of [[CXCL1]] and IL-7 was observed at 6 and 48 hours after injury, respectively. Measuring muscle [[CXCL1]] and IL-7 levels is helpful for estimating incised wound aging.

|title=Age-related pro-inflammatory and pro-angiogenic changes in human aqueous humor.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/29487806
|abstract=To reveal age-related aqueous cytokine changes in human aqueous humor. Aqueous humor was collected from 12 young children (3-6.5 years old) and 71 healthy adults (22-106 years old) with cataract but without other systemic or ocular disorders. Levels of 22 cytokines, chemokines and vascular endothelial growth factor (VEGF) were measured and analyzed. The following proteins showed significant increase from childhood to adult: interferon-gamma (IFN-γ), interleukin (IL)-13, IL-6, IL-12(p70), IL-10, [[CCL2]], [[CCL3]], [[CCL4]], [[CXCL8]], [[CXCL9]], [[CXCL10]], IFN-α2 and VEGF (all [i]P[/i]<0.05). IFN-γ, IL-13, IL-12(p70), IL-10, [[CCL3]], [[CXCL9]] and VEGF also showed moderate strength age-related increase in the adult group ([i]r[/i]>0.5). The strength of correlation between aging and [[CCL4]] were fair ([i]r[/i]=0.398). The concentrations of IL-2, IL-4, IL-5, IL-1β and [[TNF]]-α were low in both groups. From childhood to adult, the immunological milieu of the anterior chamber become more pro-inflammatory and pro-angiogenic. Such changes may represent the parainflammation state of the human eye.

|title=Changes in the expression of the Toll-like receptor system in the aging rat kidneys.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/24810370
|abstract=The mechanisms of kidney aging are not yet clear. Studies have shown that immunological inflammation is related to kidney aging. Toll-like receptors (TLRs) are one of the receptor types of the body's innate immune system. The function of the TLR system and the mechanisms by which it functions in renal aging remain unclear. In the present study, we, for the first time, systematically investigated the role of the TLR system and the inflammation responses activated by TLRs during kidney aging. We used western blot and immunohistochemistry to systematically analyze the changes in the expression and activation of the endogenous TLR ligands HSP70 and [[HMGB1]], the TLRs ([[TLR1]]-[[TLR1]]1), their downstream signaling pathway molecules MyD88 and Phospho-IRF-3, and the NF-κB signaling pathway molecules Phospho-IKKβ, Phospho-IκBα (NF-κB inhibition factor α), NF-κBp65, and Phospho-NF-κBp65 (activated NF-κB p65) in the kidneys of 3 months old (youth group), 12 months old (middle age group), and 24 months old (elderly group) rats. We used RT-qPCR to detect the mRNA expression changes of the proinflammatory cytokines [[CCL3]], [[CCL4]], [[CCL5]], [[CD80]], [[TNF]]-α, and IL-12b in the rat renal tissues of the various age groups. We found that during kidney aging, the HSP70 and [[HMGB1]] expression levels were significantly increased, and the expression levels of [[TLR1]], 2, 3, 4, 5, and 11 and their downstream signaling pathway molecules MyD88 and Phospho-IRF-3 were markedly elevated. Further studies have shown that in the aging kidneys, the expression levels of the NF-κB signaling pathway molecules Phospho-IKKβ, Phospho-IκBα, NF-κBp65, and Phospho-NF-κBp65 were obviously increased, and those of the proinflammatory cytokines [[CCL3]], [[CCL4]], [[CCL5]], [[CD80]], [[TNF]]-α, and IL-12b were significantly upregulated. These results showed that the TLR system might play an important role during the kidney aging process maybe by activating the NF-κB signaling pathway and promoting the high expression of inflammation factors.

|title=Interleukin-7 levels in synovial fluid increase with age and MMP-1 levels decrease with progression of osteoarthritis.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/22206448
|abstract=Little is known about biochemical mediators that correlate with the initiation and progression of knee osteoarthritis (OA). We therefore valuated the roles of cytokines and metalloenzymes in knee OA in relation to OA grading, age, and BMI. A multiplex ELISA-based immunoassay (Luminex technology) was used to measure biochemical mediators in the synovial fluid (SF) of 82 patients undergoing knee surgery. All patients were classified according to age, BMI, and OA grade. 24 patients had no signs of OA (knee reconstruction surgeries). The mediators that were tested for included interleukins (IL-1Ra, IL-6, IL-7, and IL-18), chemokines (CCL2 (MCP-1), [[CCL3]] (MIP-1a), and [[CXCL8]] (IL-8)), growth factors (HGF and VEGF), and matrix metalloproteinases (MMP-1, MMP-2, MMP-9, and MMP-13). There was a correlation between IL-7 levels in SF and age (p < 0.01). The 11 highest IL-7 levels were seen in patients who were aged between 59 and 72 but had different OA grades. In contrast, all patients who had severe OA in all 3 knee compartments (pan-OA) had only low or medium IL-7 levels. There was a negative correlation between MMP-1 levels in synovial fluid and grade of OA (p < 0.001). Correlation studies between pairs of mediators revealed two groups of mediators that are important in OA progression, dominated by MCP-1 and IL-1Ra. IL-7 levels in SF are elevated in elderly people suffering from OA of different grades, but they are depressed in patients with severe 3-compartment OA, possibly due to widely impaired chondrocytes embedded in the affected cartilage tissue. The observed decrease in MMP-1 levels in SF, which is dependent on the severity of OA, may be caused by deterioration of superficial cartilage layers during progression of OA.

|title=Fat-storing multilocular cells expressing [[CCR5]] increase in the thymus with advancing age: potential role for [[CCR5]] ligands on the differentiation and migration of preadipocytes.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/20046229
|abstract=Age-associated thymic involution is characterized by decreased thymopoiesis, adipocyte deposition and changes in the expression of various thymic microenvironmental factors. In this work, we characterized the distribution of fat-storing cells within the aging thymus. We found an increase of unilocular adipocytes, ERTR7( ) and [[CCR5]](  )fat-storing multilocular cells in the thymic septa and parenchymal regions, thus suggesting that mesenchymal cells could be immigrating and differentiating in the aging thymus. We verified that the expression of [[CCR5]] and its ligands, [[CCL3]], [[CCL4]] and [[CCL5]], were increased in the thymus with age. Hypothesizing that the increased expression of chemokines and the [[CCR5]] receptor may play a role in adipocyte recruitment and/or differentiation within the aging thymus, we examined the potential role for [[CCR5]] signaling on adipocyte physiology using 3T3-L1 pre-adipocyte cell line. Increased expression of the adipocyte differentiation markers, PPARgamma2 and aP2 in 3T3-L1 cells was observed under treatment with [[CCR5]] ligands. Moreover, 3T3-L1 cells demonstrated an ability to migrate in vitro in response to [[CCR5]] ligands. We believe that the increased presence of fat-storing cells expressing [[CCR5]] within the aging thymus strongly suggests that these cells may be an active component of the thymic stromal cell compartment in the physiology of thymic aging. Moreover, we found that adipocyte differentiation appear to be influenced by the proinflammatory chemokines, [[CCL3]], [[CCL4]] and [[CCL5]].

|title=Mononuclear phagocyte-derived interleukin-10 suppresses the innate pulmonary granuloma cytokine response in aged mice.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/17631521
|abstract=Granulomas are sequestration responses observed in a wide variety of clinical conditions, including mycobacterial infection. We previously reported impaired adaptive, Th1 cell-mediated pulmonary granuloma formation in response to bead-immobilized Mycobacterium bovis-purified protein derivative in aged mice. To reveal determinants of age-related immune deficits, the present study examined the effect of aging on early innate stage pulmonary granuloma formation. Aged mice formed more neutrophil-rich innate granulomas with augmented [[CXCL2]] expression followed by a pattern of rapid decay of tumor necrosis factor-alpha, interleukin (IL)-6, [[CCL3]], and [[CXCL2]]. This was associated with enhanced IL-10 expression. Blockade of IL-10 signaling with anti-IL-10 receptor antibody reversed the age-related decay. Intracellular flow cytometric analysis revealed that CD11b( )Gr-1( /-) mononuclear phagocytes were the primary leukocyte sources of IL-10 in lungs, and their numbers were increased in aged mice. When exposed to purified protein derivative in vitro, young and old CD11b( )Gr-1( /-) mononuclear phagocytes from blood or lung had comparable IL-10 expression, suggesting in vivo signals in the aged environment enhanced the number of IL-10-producing cells in the aged lung. Our findings reveal a novel mechanism of age-associated IL-10 mediated pulmonary immune suppression with the potential to alter downstream adaptive immunity.
