Can someone clue me in as to what a type 1 immune response is?

It doesn't seem to be an official term, more like jargon that's used in an immunology lab. I"m having trouble finding any links for "type 1 immune response" that aren't related to type 1 diabetes.

Any help would be appreciated.

IIRC there are hypersensitivity disorders given the numbers I to IV, with I being common allergic responses, e.g. asthma, whilst Type IV represented delayed type hypersensitivity to antigens. Maybe if you use these as search strings it may relate to what you are looking for.

That was another question I had: Is a type 1 immune response the same as saying Type 1 hypersensitivity?

I've found some info from this paper (and am going through it now):

Thanks for the response.

From a very prelliminary scan of the paper, it mentions Type I as including inflammatory responses to graft rejection, autoimmune reactions (also known as Type II and III hypersensitivity) and also seems to include normal Tcell-B cell interactions to antigen presentation, so the definition must have broadened since the 'old days':

More generally, the broad range of type 1 immune responses such as infectious diseases (intra and extracellular pathogens) or autoimmunity (diabetes, multiple sclerosis and lupus) that involve or require IFN-γ suggest a role for Pin1 in these processes as well.

Also found this ks:

Quote

Hypersensitivity (also called hypersensitivity reaction) refers to undesirable reactions produced by the normal immune system, including allergies and autoimmunity. These reactions may be damaging, uncomfortable, or occasionally fatal. Hypersensitivity reactions require a pre-sensitized (immune) state of the host. The four-group classification was expounded by P. H. G. Gell and Robin Coombs in 1963.[1]

After refreshing my memory it is not type 1 and type 2 etc immune responses, it is more specifically type 1 and type 2 etc hypersensitivity.

Type 1 hypersensitivity is specifically mediated by IgE antibodies that bind to tissue mast cells and trigger them to degranulate. In so doing the release a variety of substances that trigger an inflammatory response - edema(sweeling), caplillary dilation(redening) and accumulation of neutrophils(pus formation)

This can be localised, e.g. after receiving some vaccines and mosquito bites or systemic, e.g. analphalactic shock.
