Age-related changes in the immune system increase susceptibility to infectious diseases. Vaccines are an important tool to prevent infection or boost immunological memory; however, vaccines are less effective in aged individuals. In order to protect our aging population from the threat of infectious diseases, we must gain a better understanding of age-related alterations in the immune response at the site of infection.

Article Synopsis
  • - The study investigates the risk factors for tuberculosis (TB) specifically in elderly Hispanics, highlighting that aging and diabetes may contribute to TB risk, but existing data on these individuals is limited.
  • - A total of 646 participants were included, revealing higher rates of latent TB infection (LTBI) in elderly community controls compared to younger adults, but gender, smoking, and low body mass index (BMI) were major risk factors for TB.
  • - Surprisingly, type 2 diabetes did not show a strong link to TB risk, whereas BCG vaccination at birth offered protective benefits; this emphasizes the need for more research on TB in older populations.

Individuals over the age of 65 are highly susceptible to infectious diseases, which account for one-third of deaths in this age group. Vaccines are a primary tool to combat infection, yet they are less effective in the elderly population. While many groups have aimed to address this problem by studying vaccine-induced peripheral blood responses in the elderly, work from our lab and others demonstrate that immune responses to vaccination and infectious challenge may differ between tissue sites and the periphery.

Unlabelled: The life expectancy of persons with spinal cord injury (SCI) is increasing due to advances in medicine and technology. As a result, there is a higher incidence of age-associated illnesses in this population. Degenerative joint disease is a common age-associated illness that causes pain and thus, in persons with SCI above the T6 level, can serve as a noxious stimulus to trigger autonomic dysreflexia (AD).

Depression is a common, potentially devastating comorbidity in youth with attention-deficit/hyperactivity disorders (ADHD). Various environmental adversities are well-described as correlates of depression in general pediatric populations, but not in youth with ADHD. In 104 adolescents with ADHD, we examined potential environmental correlates of lifetime depression, including trauma exposure, recent negative life events and current parent-child conflict, along with current and past ADHD severity and current impairment.

A-kinase anchoring protein mediates TRPV1 thermal hyperalgesia through PKA phosphorylation of TRPV1.

Pain

September 2008

Department of Oral and Maxillofacial Surgery, University of Texas Health Science Center of San Antonio, MC 7908, 7703 Floyd Curl Dr., San Antonio, TX 78229-3900, USA Department of Endodontics, University of Texas Health Science Center of San Antonio, San Antonio, TX, USA Department of Cellular and Structural Biology, University of Texas Health Science Center of San Antonio, San Antonio, TX, USA Department of Pharmacology, University of Texas Health Science Center of San Antonio, San Antonio, TX, USA.

Certain phosphorylation events are tightly controlled by scaffolding proteins such as A-kinase anchoring protein (AKAP). On nociceptive terminals, phosphorylation of transient receptor potential channel type 1 (TRPV1) results in the sensitization to many different stimuli, contributing to the development of hyperalgesia. In this study, we investigated the functional involvement of AKAP150 in mediating sensitization of TRPV1, and found that AKAP150 is co-expressed in trigeminal ganglia (TG) neurons from rat and associates with TRPV1.
