Cytokines are small proteins in the immune system that act as chemical messengers between cells.

New technologies are coming to the fore that allow interrogation of the types of cells interacting with tumors, in particular providing intelligence on the broad variety of complex associations between tumor cells and the immune system.

Kipnis and his team first suspected a link between the immune system and social behavior when they found that mice lacking T cells, key components of the immune system, show little interest in their peers.

In the Dec. 1 issue of Science, the team from the MGH Center for Systems Biology describes a «crosstalk» between lung tumors and bone marrow, which leads to the generation of a type of immune cell that travels to the tumor and promotes its progression.

The research team, a collaborative partnership between the groups of Professor Gabrielle Belz of Melbourne's Walter and Eliza Hall Institute, and Professor Eric Vivier at the Centre d'Immunologie de Marseille - Luminy, France, found that innate lymphoid cells (ILCs) are crucial for protecting against bacterial infection in people with compromised immune systems.

Now, in a study recently published in the journal PLOS ONE, a team of scientists from VCU Massey Cancer Center have shown a genetic relationship between the reactivation of hCMV and the onset of graft - versus - host disease (GVHD), a potentially deadly condition in which the immune system attacks healthy tissue following a bone marrow or stem cell transplant.

Walford's new research is based on the fact that in mice and humans, the immune system malfunctions during aging, losing the ability to distinguish between healthy cells and invasive pathogens such as bacteria and viruses.

To measure the differences in immune system function between the two groups of older mice, the researchers examined the lungs to assess damage, counted the number of bacteria in the lungs, and calculated the number of the white blood cells (neutrophils).

Hence, we merged our expertise in evolutionary biology and immunology to study the complex interactions between the vertebrate immune system, composed of a myriad of different cells, and the gut microbiota, composed of another myriad of different bacteria.

Hypothesis driven approaches to vaccinology can utilise the knowledge gained from mechanistic mouse models and our molecular understanding of intrinsic defects to human cells.5 However, caution is required when extrapolating data from murine models, as there are substantial differences between immune ageing in mice and humans.6 Nevertheless, model systems and ex vivo analyses of molecular alterations in aged human cells have identified multiple changes in the vaccination response with age and the aged immune system in general.

Our laboratory is interested broadly in the interface between the innate and adaptive immune systems, and the unique subsets of T lymphocytes that bridge these systems by adopting properties that are very characteristic of innate immune cells.

In that month, there are millions of chance encounters between cells of the immune system and the vaccine, and then a period where many times as many cells randomly stitch and mutate bits of DNA in an attempt to build working antibodieIn that month, there are millions of chance encounters between cells of the immune system and the vaccine, and then a period where many times as many cells randomly stitch and mutate bits of DNA in an attempt to build working antibodiein an attempt to build working antibodies.

Under the guidance of immunologist Vitalij Yurin, he immersed himself in the study of the interplay between the immune system's main actors: T cells and B cells.

Because double - stranded viral RNA is typically longer than that naturally found in cells, Hur surmised that a mechanism that uses length to distinguish between viral and cellular RNA might underlie the immune system's discriminatory power.

A disparity between these cell types, when there are too many Th17 and not enough Tregs, can lead to a hyperactive immune system, resulting in inflammation, tissue damage, and autoimmune disease.
