Preliminary results of a small clinical trial show that a vaccine used to treat women with high-grade precancerous cervical lesions triggers an immune cell response within the damaged tissue itself. The Johns Hopkins scientists who conducted the trial said the finding is significant because measuring immune system responses directly in the lesions may be a more accurate way to evaluate so-called

Ive read this week that the spleen has been identified as a repository of monocytes - immune cells responsible for repairing damaged tissue (assuming that my very limited and brief understanding of the article is accurate). I deduce from this that part of Wolverines mutant abilities is a hyperactive spleen ...
Using advanced intravital microscopy to visualize immune cell movement within the tissues, investigators at the Peter Doherty Institute for Infection and Immunity, Melbourne have discovered that the neurotransmitter noradrenaline produced by the sympathetic nervous system causes a dramatic paralysis of immune cell movement. The authors show that noradrenaline released during stress alters blood flow in tissues that temporarily starves leukocytes of the oxygen that they need to move. Impaired leukocyte mobility contributes to poor immunity to virus infection, malaria infection and cancer in mouse models. . . .

Aflatoxins are known to have a hepatotoxic effect in poultry and also a hepatocarcinogenic effect in exposed animals. The most common pathological lesions associated with aflatoxicosis in poultry are found in the liver, lymphoid organs, and testes, often occurring over a period of chronic exposure. In acute-subacute aflatoxicosis, the liver appears enlarged, pale yellow in color, friable, and usually the gall bladder is also enlarged and filled with bile (see Figure 8). The pancreas is usually small and depigmented and there could be hemorrhages on subcutaneous tissue and muscles. In chronic aflatoxicosis, the liver is small, firm, and rounded. Sometimes this organ is very small, rounded, and rubbery, and often complicated with ascites and hydropericardium. The other consistent lesions in aflatoxicosis can be found in the bursa of Fabricius, thymus, and spleen, all of which appear smaller than normal. In male parent stock breeder birds, the size of the testes could also be significantly ...

Production animals are faced with frequent immune system challenges that include not only microbial infections such as mastitis but also chronic gut inflammation caused by feed changes and heat stresses. The energy cost of fueling these immune cell responses has been difficult to calculate and even its approximate magnitude has been unclear.. Recently, a team of researchers from Iowa State University led by Lance Baumgard performed intriguing experiments using lactating Holstein cattle to determine the magnitude of the energy cost of an immune response[1].. The researchers selected lactating Holstein cattle and subjected them to three treatments. The first animal group received an intravenous control treatment consisting of a saline solution. The second group received a small amount of a very potent bacterial cell wall component, lipopolysaccharide or LPS, which is known to induce a strong immune response in nearly all animals, including cattle. The LPS was used to trick the cattle immune system ...
Challenges, however, remain to perfect these therapies for use in the clinic for cancer treatment. The nature of these challenges are scientific, clinical and regulatory. Scientific challenges include defining the appropriate tumor types for an appropriate immunotherapy, the conditions under which various cells of the immune system would be activated and determining how best to manipulate them to allow for maximum tumor cell destruction, finding better ways to circumvent cancer cell suppression of immune cell responses and using new techniques to prevent or ameliorate the nonspecific injury to normal tissue that can occur as a side effect of immunotherapeutic treatment ...
Two cohorts of patients with a phenotype of HIV resistance exist in France. The ANRS CO15 ALT cohort was set up in 1994. 71 patients were enrolled defined on immunological criteria: CD4 T cell count above 600/mm3 with a stable or increasing count (positive or zero slopes) on at least three consecutive exams performed during the last 5 years whatever the viral load was, with a known HIV infection for at least 8 years. A consortium of research teams has studied the immunovirological characteristics of these patients. After 16 years of follow-up, 6 patients are still actively followed. The main results have shown the lack of deletion in viral genes nor any functional viral defects, a small size for the viral reservoir, and distinctive genetic characteristics of the host (HLA, chemokines) which lead to potent immune cell responses associated with virus control.. The ANRS CO18 HIV Controller cohort set up in 2009 is stemming from the French National Observatory of HIV Controllers which was active ...

The Suppressor of cytokine signaling (SOCS) and cytokine-inducible SH2 proteins are a family of intracellular proteins which regulate the immune cell responses to cytokines. SOCS1 acts to suppress dendritic cell (DC) as well as T cell hyperactivation following cytokine signaling by inhibiting JAK tyrosine kinase, a kinase necessary for type I and II cytokine receptors to initiate signaling, by directly binding to the catalytic domain of the kinase. SOCS1 also possesses E3 ubiquitin protein ligase activity that results in the polyubiquitination of its target proteins and subsequent degradation by the proteosome. It is through this method that SOCS1 negatively regulates signaling by Toll-like receptors TLR2 and TLR4 by mediating the degradation of the TLR signaling adaptor protein TIRAP ...
