Circulating autoantibody to a 48-kD nuclear protein in neurons and astrocytes of the human and bovine cerebrum were present in the serum of a demented patient with an autoimmune disorder. Other human visceral organs, dorsal root ganglion cells, neuroblastoma and glioblastoma cell lines, and rat cerebrum did not react with the patient's serum. No sera from age-matched controls, including those with Alzheimer's disease, reacted with the 48-kD protein. Only the mature neurons and astrocytes of humans and some mammals express the 48-kD protein. This antibody may be responsible for the patient's demented condition.

Forkhead box protein P3 (FOXP3) contributes to a unique transcriptional signature and serves as a functional marker of CD4(+)CD25(+) natural regulatory T cells. Dysfunction of FOXP3 in human is associated with fatal autoimmune disease known as immunodysregulation, polyendocrinopathy, enteropathy, X-linked syndrome (IPEX) or X-linked autoimmunity-allergic disregulation syndrome (XLAAD). FOXP3 also can act as a breast tumor suppressor of the v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 (neuro/glioblastoma derived oncogene homolog (avian)) (Her2/neu) gene. While the suppressive functions of FOXP3 in maintaining the immune balance between tolerance and autoimmunity are obvious, the underlying molecular mechanism remains almost entirely undefined. Recent studies indicate that FOXP3 may form a dynamic superamolecular complex with a variety of molecular partners including transcription factors and enzymatic proteins to regulate transcription. How the FOXP3 ensemble changes in response to T-cell receptor signals and/or proinflammatory signal remains unclear although work from this laboratory has revealed its complexity. Structural information on FOXP3 complex may offer novel functional insights, as well as facilitate the development of rational means to modulate regulatory T-cell function in various human diseases.

Chemokines and chemokine receptors play an important role in immune homeostasis and surveillance. Altered or defective expression of chemokines and/or chemokine receptors could lead to a disease state including autoimmune disorder or cancer. Tumors from glioblastoma, melanoma, and neuroblastoma secrete high levels of chemokines that can promote tumor growth and progression or induce stromal cells present in the tumor microenvironment to produce cytokines or chemokines which, in turn, can regulate angiogenesis, tumor growth, and metastasis. On the other hand, chemokines secreted by tumor or stromal cells can also attract leukocytes such as dendritic cells, macrophages, neutrophils, and lymphocytes which may downmodulate tumor growth. New therapies that are aimed at limiting tumor growth and progression by attracting immune effector cells to the tumor site with chemokines may hold the key to the successful treatment of cancer, although this approach may be hampered by possible tumor growth-stimulating effects of chemokines.

Down's syndrome (DS; also known as trisomy 21; T21) is caused by a triplication of all or part of human chromosome 21 (chr21). DS is the most common genetic cause of intellectual disability attributable to a naturally-occurring imbalance in gene dosage. DS incurs huge medical, healthcare, and socioeconomic costs, and there are as yet no effective treatments for this incapacitating human neurogenetic disorder. There is a remarkably wide variability in the 'phenotypic spectrum' associated with DS; the progression of symptoms and the age of DS onset fluctuate, and there is further variability in the biophysical nature of the chr21 duplication. Besides the cognitive disruptions and dementia in DS patients other serious health problems such as atherosclerosis, altered lipogenesis, Alzheimer's disease, amyotrophic lateral sclerosis (Lou Gehrig's disease), autoimmune disease, various cancers including lymphoma, leukemia, glioma and glioblastoma, status epilepticus, congenital heart disease, hypotonia, manic depression, prostate cancer, Usher syndrome, motor disorders, Hirschsprung disease, and various physical anomalies such as early aging occur at elevated frequencies, and all are part of the DS 'phenotypic spectrum.' This communication will review the genetic link between these fore-mentioned diseases and a small group of just five stress-associated microRNAs (miRNAs)-that include let-7c, miRNA-99a, miRNA-125b, miRNA-155, and miRNA-802-encoded and clustered on the long arm of human chr21 and spanning the chr21q21.1-chr21q21.3 region.
