Responses to the synthetic terpolymer L-glutanmic acid, L-lysine, L-phenylalanine (GLphi) and hapten derivatives thereof are controlled by two complementing H-2 linked Ir genes in the mouse. F1 hybrids derived from two different nonresponder strains (one of which possesses the alpha and the other beta Ir-GLphi gene) are phenotypic responders to GLphi and 2,4-dinitrophenyl (DNP)-GLphi. Moreover, spleen cells from DNP-GLphi-primed F1 mice can adoptively transfer secondary anti-DNP antibody responses to irradiate been challenged with DNP-GLphi. When, however, GLphi-primed F1 helper T cells are transfered together with the DNP-specific F1 B cells that had been primed in separate mice altogether by DNP coupled to an unrelated protein carrier, such mixtures failed to develop adequate adoptive secondary anti-DNP responses to DNP-GLphi. This contrasted with the ability of the same GLphi-primed F1 T cells to provide helper activity for DNP-primed B cells from responder recombinant B10.A (5R) mice. More important, the apparent defect of GLphi-primed F1 T cells in providing help for DNP-primed F1 B cells (primed to a DNP-protein conjugate) could be readily overcome by using DNP-primed B cells from donor F1 mice primed with DNP-GLphi.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Systemic Juvenile Idiopathic Arthritis

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, but also fevers and skin rashes. Here is the latest on this disease.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.

Chronic Traumatic Encephalopathy

Chronic Traumatic Encephalopathy (CTE) is a progressive degenerative disease that occurs in individuals that suffer repetitive brain trauma. Discover the latest research on traumatic encephalopathy here.
