In infection experiments, C. jejuni was more invasive in the presence of B. fragilis and this increase is due to fucosidase activity. We conclude that C. jejuni fuc + strains are dependent on exogenous fucosidases for increased growth and invasion.
Most evidence concerning aging ignores women's sexual orientation, yet sexual orientation-related discrimination across the life course may influence older lesbian and bisexual women's risk for poorer health. Understanding aging-well in this group is vital to development, testing, and implementation of evidence-based health promotion programming and services for aging sexual minority women.

Data were from the Women's Health Initiative (N = 15691; heterosexual n = 15002, lesbian n = 440, bisexual n = 249) extension study. Multivariable linear and logistic regression tested associations between sexual orientation and indicators of successful, effective and optimal aging-well in age-stratified groups of women (60-74 and 75+).

Lesbians aged 60-74 were more likely (OR 1.59, 95%CI 1.16, 2.18) to report good self-mastery, more social support (b = 2.92, 95% CI, 1.99-3.85), and greater likelihood of enjoying life (OR 1.46, 95% CI 1.06, 2.01) compared with heterosexual women. Bisexual women aged 75+ reported increased personal growth (b = 1.09, 95% CI, 0.23-1.95) compared to heterosexuals. While lesbians aged 75+ had greater likelihood of living in a nursing home (OR = 1.96; 95% CI, 1.01-3.82) and were less likely to be happy at least most of the time (OR .68, 95% CI, 0.49, 0.99), they reported greater self-mastery (OR = 1.55; 95% CI, 1.06,2.26) than their heterosexual peers.

Aging-well is not the same for all women. Health promotion programs may consider maximizing sexual minority women's internal and external resources-including social supports, self-mastery, and personal growth-to promote wellness in older age.

Assess family caregivers' primary appraisal of stressors related to COVID-19 stay-at-home orders, secondary appraisal of resources and support availability, and use of coping strategies as predictors of perceived role overload during the stay-at-home phase of the pandemic.

Telephone interviews with 53 family caregivers of persons with dementia from rural Virginia two weeks after enactment of the governor's stay-at-home order using structured and open-ended questions.

Caregivers who were more concerned about the COVID-19 pandemic were at greater odds of experiencing high role overload than those who recognized positive aspects of the pandemic, as were those who received insufficient support from family and friends.

Use of the transactional model of stress responses yielded important insights about families coping with dementia. Elenbecestat Caregivers' perceptions of the pandemic's impact varied, with differential effects on their well-being.

Depression is one of the most common forms of mental illness and also a leading cause of disability worldwide. Developing novel antidepressant targets beyond the monoaminergic systems is now popular and necessary. LIM kinases, including LIM domain kinase 1 and 2 (LIMK1/2), play a key role in actin and microtubule dynamics through phosphorylating cofilin. Since depression is associated with atrophy of neurons and reduced connectivity, here we speculate that LIMK1/2 may play a role in the pathogenesis of depression.

In this study, the chronic unpredictable mild stress (CUMS), chronic restraint stress (CRS), and chronic social defeat stress (CSDS) models of depression, various behavioral tests, stereotactic injection, western blotting, and immunofluorescence methods were adopted.

CUMS, CRS, and CSDS all significantly enhanced the phosphorylation levels of LIMK1 and LIMK2 in the medial prefrontal cortex (mPFC) but not the hippocampus of mice. Administration of fluoxetine, the most commonly used selective serotonin reuptake inhibitor in clinical practice, fully reversed the effects of CUMS, CRS, and CSDS on LIMK1 and LIMK2 in the mPFC. Moreover, pharmacological inhibition of LIMK1 and LIMK2 in the mPFC by LIMKi 3 infusions notably prevented the pro-depressant effects of CUMS, CRS, and CSDS in mice.

In summary, these results suggest that LIMK1/2 in the mPFC has a role in chronic stress-induced depressive-like effects in mice and could be a novel pharmacological target for developing antidepressants.

Persistent antigen leads to CD8 T-cell exhaustion, where proliferation/self-renewal and killing are divided within distinct subsets of CD8 T cells in the tumor. CD8 T-cell responses in chronic antigen settings must be maintained for long periods of time, suggesting that mechanisms that regulate chronic CD8 T-cell responses may differ from those in acute settings. Currently, factors that regulate the maintenance of stem-like CD8 T cells in the tumor or their differentiation into terminally differentiated cells are unknown. In this review, we discuss the role of dendritic cells in the activation and differentiation of CD8 T-cell subsets within secondary lymphoid tissue and tumors. In addition, we examine changes in CD4 T-cell differentiation in response to chronic antigens and consider how subset-specific mechanisms could assist the stem-like and terminally differentiated CD8 T-cell subsets. Finally, we highlight how tumor-infiltrating CD4 T cells and dendritic cells interact with CD8 T cells within organized lymphoid-like areas in the tumor and propose a CD8 T-cell differentiation model that requires the collaboration of CD4 T cells and dendritic cells. These organized interactions coordinate the anti-tumor response and control disease progression by mechanisms that regulate CD8 T-cell differentiation, which permit the maintenance of an effective balance of stem-like and terminally differentiated CD8 T cells.
